We’re all familiar with the idea that Lent is forty days long, and it used to be true that Lent involved forty days excluding Sundays, though this isn’t true now, given revisions to the Church’s liturgical calendar.

The length of Lent is inspired by the forty days that Jesus spent in the wilderness before he began his public ministry (Matt. 4:1-11, Mark 1:12-13, Luke 4:1-13).

However, there’s another forty days connected with Jesus, and we read about them at the beginning of Acts:

To them [the apostles] he presented himself alive after his passion by many proofs, appearing to them during forty days, and speaking of the kingdom of God (Acts 1:3).

Jesus then instructed the apostles to remain in Jerusalem until they received the Holy Spirit (Acts 1:4-5). This happened on Pentecost, fifty days after his Crucifixion on Passover.

These forty days are interesting in their own right, and many Christians have wondered about them. For example, why did Jesus only stay forty days and not the full fifty? Why leave when he did?

We aren’t told, but a likely explanation is that he was using the forty days as a parallel to his time in the wilderness. Just as he spent forty days in the desert to prepare for his ministry, he now stayed with the apostles for forty days, preparing them for their ministry.

The tradition that he remained with them forty days was not universal in the early Church, however. The second century Church Father Irenaeus of Lyons recorded that the Valentinian Gnostics claimed Jesus remained with the disciples for eighteen months (Against Heresies 1:3:2). The same view was held by another sect known as the Ophites (1:30:14).

Paulist Press’s translation of Irenaeus finds the origin of this counter tradition obscure. An editorial note on 1:30:14 says “How this strange error arose is a mystery,” and a note on 1:3:2 says, “Perhaps it was in some apocryphal work.”

Though the editors of the Paulist translation are unaware of it, this is actually the correct answer. There was an early noncanonical work that contained this tradition. The Ascension of Isaiah, which was written about the year A.D. 67, states:

And when he [Jesus] has plundered the angel of death, he will rise on the third day and will remain in that world for five hundred and forty-five days (Ascension of Isaiah 9:16).

Five hundred and forty-five days works out to just over eighteen months, and this may have been the origin of the Valentinian and Ophite believe that Jesus remained with the disciples for that amount of time.

Still, not all agreed. The third century Gnostic work called Pistis Sophia holds that Jesus remained with the disciples for an astonishing eleven years!

It came to pass, when Jesus had risen from the dead, that he passed eleven years discoursing with his disciples (Pistis Sophia 1:1).

However, the canonical book of Acts is divinely inspired, and Luke was an excellent historian, so we should go with him. Forty days it was.

What was Jesus doing in this time? According to various Gnostic sects, he was imparting their secret Gnostic teachings to the apostles.

According to their idea, Jesus gave two sets of teachings. The first was an exoteric or public set of teachings that the apostles passed down to the bishops to be shared with the faithful in general, and the second was an esoteric or secret set of teachings that were to be shared only with a select few (the Gnostics themselves).

This “two sets of teachings” idea was to justify how the Gnostics could have teachings coming from Jesus that were manifestly different than those preached by the bishops.

Because books were fantastically expensive in the ancient world (with a single copy of Matthew costing the equivalent of more than $2,000), the Gnostics didn’t bother writing Gospels in our sense—that is, documents that told the full story of Jesus.

Instead, they supplemented the canonical Gospels by writing documents that zoomed in on particular moments in Jesus’ life. An example is the second century Gospel of Mary, in which—after the Resurrection—Jesus gave “Mary” (likely Mary Magdalen) secret Gnostic teachings.

However, even secular scholars acknowledge that Gnostic documents are too late to contain accurate information about Jesus’ life and teachings.

We also do not have writings from the Church Fathers that are early enough to provide reliable information about the forty days. Acts 1:3 is barely mentioned in the orthodox Christian writings of the second and third centuries, and when it is mentioned, we aren’t given any new information about the period.

So once again, we’re back to the canonical works if we wish to obtain that.

At the beginning of Acts, Luke tells us that Jesus essentially did three things during the forty days: (1) “he presented himself alive after his passion,” (2) “by many proofs,” and (3) “speaking of the kingdom of God.”

He may well have done other things, too, like spending time with the disciples, sharing table fellowship with them, and even possibly celebrating the Eucharist. But these are the three things Luke tells us he did.

When it comes to presenting himself alive, Luke mentions only two events from this period in Acts. The first is the instruction to remain in Jerusalem until the apostles receive the Holy Spirit (Acts 1:4-5), and the second is the Ascension (Acts 1:6-11).

But Luke tells us more in his Gospel, indicating that Jesus appeared to the two disciples (one of whom was Cleopas) on the road to Emmaus (Luke 24:13-35), that he appeared to Peter (Luke 24:34), that he appeared to the apostles “and those who were with them” (Luke 24:36-49), and that he ascended before them (Luke 24:50-53).

We can expand on these appearances by consulting other canonical texts. Matthew records that Jesus also appeared to the women who discovered the empty tomb (Matt. 28:9-10) and that he appeared to the Eleven in Galilee, where he gave them the Great Commission (Matt. 28:16-20).

John reports that Jesus appeared to Mary Magdalen, in particular, on the morning of the Resurrection (John 20:11-17) and that he appeared to the other core disciples (less Thomas) later that day (John 20:19-23). He also appeared to the Twelve including Thomas a week later (John 20:26-29), and he later appeared to a group of seven disciples at the Sea of Galilee (John 21:1-22).

The longer ending of Mark confirms many of these appearances, including the one to Mary Magdalen (Mark 16:9), the one on the road to Emmaus (Mark 16:12), and another to the Eleven (Mark 16:14), as well as the giving of the Great Commission (Mark 16:15-18) and the Ascension (Mark 16:19).

We also have evidence from St. Paul, who records the same appearance to Peter that Luke mentioned (1 Cor. 15:5a) and a subsequent appearance to the Eleven (1 Cor. 15:5b).

Paul strikingly says that “Then he appeared to more than five hundred brethren at one time, most of whom are still alive, though some have fallen asleep” (1 Cor. 15:6)—that is, by the time 1 Corinthians was written around A.D. 53.

After this appearance to more than five hundred, Paul says, “Then he appeared to James, then to all the apostles” (1 Cor. 15:7)—indicating first an appearance to James “the brother of the Lord” and then another appearance to the Twelve (which would have, by this time, included Judas’s replacement, Matthias; see Acts 1:12-26).

Finally, Paul says, “Last of all, as to one untimely born, he appeared also to me” (1 Cor. 15:8). However, Luke indicates that this occurred long after the Ascension and thus after the forty days were over (Acts 9:1-19).

When it comes to the “many proofs” that Jesus was alive, Luke records two of them in his Gospel. The first is this:

[The Eleven and those who were with them] were startled and frightened and supposed that they saw a spirit. And he said to them, “Why are you troubled, and why do questionings rise in your hearts? See my hands and my feet, that it is I myself; handle me, and see; for a spirit has not flesh and bones as you see that I have.” And when he had said this he showed them his hands and his feet (Luke 24:37-40).

The second is:

And while they still disbelieved for joy, and wondered, he said to them, “Have you anything here to eat?” They gave him a piece of broiled fish, and he took it and ate before them (Luke 24:41-43).

John appears to record more detailed accounts of these same two proofs, elaborating that the first occurred when Jesus invited Thomas to touch the wounds in his hands and side (John 20:24-28) and when he appeared to seven disciples at the Sea of Galilee and ate charbroiled fish with them (John 21:9-14).

When it comes to “speaking of the kingdom of God,” we are not told specifically what Jesus said.

The Gnostics obviously had their own (completely unreliable) theories. However, a more secure basis is found in the canonical works that we have.

The kingdom of God is a prominent theme in the canonical Gospels, and we are told that the disciples did not understand things that he told them before the Resurrection, including what he meant when he predicted that he would die and rise again (Mark 9:30-32), as well as other matters (John 2:21-22).

However, on the road to Emmaus, “beginning with Moses and all the prophets, he interpreted to them in all the Scriptures the things concerning himself” (Luke 24:27). Similarly, when he spoke to the apostles and those with them:

Then he said to them, “These are my words which I spoke to you, while I was still with you, that everything written about me in the law of Moses and the prophets and the psalms must be fulfilled.” Then he opened their minds to understand the Scriptures, and said to them, “Thus it is written, that the Christ should suffer and on the third day rise from the dead, and that repentance and forgiveness of sins should be preached in his name to all nations, beginning from Jerusalem” (Luke 24:44-47).

It is thus likely that in this forty-day period, Jesus reviewed many of his previous teachings about the kingdom of God and helped the disciples understand them more fully.

Did Jesus do other things in this period? It is quite possible. Near the end of his Gospel, John tells us:

Now Jesus did many other signs in the presence of the disciples, which are not written in this book (John 20:30).

Some of those signs may have occurred in the forty-day period he spent with the disciples after his resurrection.

However, whether he did so and what these signs may have been, we are not told. We must therefore leave them as an Easter mystery.

Judas Iscariot’s betrayal of Jesus is perplexing in several ways, and Christian thinkers have sought to make sense of it.

The largest question is: Why did Judas perform the betrayal? What was his motive?

The Gospels give us some clues. One is that Satan was working on Judas (Luke 22:3, John 13:2, 27). However, this explains the action from a superhuman point of view and does not address why—on a human level—Judas would choose to betray Jesus.

A possible human motive may have been greed. John indicates that Judas was greedy and had previously committed theft to obtain money (John 12:5-6), and Matthew portrays Judas as telling the chief priests, “‘What will you give me if I deliver him over to you?’ And they paid him thirty pieces of silver. And from that moment he sought an opportunity to betray him” (Matt. 26:15-16). Mark and Luke also mention a commitment to pay Judas (Mark 14:11, Luke 22:5).

This suggests at least that Judas wanted to be compensated for the deed, but that doesn’t mean it was his primary motive. Why would someone who had followed Jesus for three years suddenly decide to betray his master? Is the opportunity for some quick cash really a sufficient motive?

Many have thought that it is not, and they have proposed additional reasons. One is the idea that Judas was actually trying to help Jesus fulfill his messianic destiny by bringing him into contact with the Jewish authorities. This view would tend to rehabilitate Judas, as he thought he was doing a good thing.

In favor of such a view, Judas could be seen as not aware of the fact he’s betraying Jesus, for when Jesus predicts at the Last Supper that one of the Twelve will betray him, Judas—along with the others—asks, “Is it I, Master?” (Matt. 26:25; cf. 26:22). Also, “when Judas, his betrayer, saw that Jesus was condemned, he changed his mind and brought back the thirty pieces of silver to the chief priests and the elders, saying, ‘I have sinned by betraying innocent blood’” (Matt. 27:3-4). So maybe Judas just meant to put Jesus in contact with the chief priests and didn’t realize they would condemn him.

Against this view is the fact that Judas “had given them a sign, saying, ‘The one I shall kiss is the man; seize him and lead him away safely’” (Mark 14:44). The use of a covert sign—as opposed to making a simple introduction—and the instruction to seize Jesus indicates consciousness of betrayal.

However, another messianic motive is possible. No doubt, Judas—like the other disciples—expected Jesus to be a political Messiah who would kick out the Romans and restore national sovereignty to Israel (cf. John 6:15, 11:48-50; Acts 1:6). However, Jesus did not intend to be this type of Messiah. Perhaps Judas disagreed, and by forcing him into a confrontation with the chief priests, Judas was hoping to force him back onto what he regarded as the proper path for the Messiah—only to see Jesus condemned instead.

Another possible motive is anger and resentment. It is clear from various passages in the New Testament that some disciples (Peter, James, John, and Andrew) were closer to Jesus than others, and Judas is always listed last among the Twelve (Matt. 10:1-4, Mark 3:13-19, Luke 6:12-16). Perhaps Judas’s lower status had come to grate on him after three years, and—under the influence of Satanically inspired envy and resentment—he decided to prove that he was a person of importance after all.

What we can say with confidence is that on the superhuman level Satan was involved and on the human level greed was involved, but beyond that, all we can do is speculate.

Whatever Judas’s exact motive, a careful reading of the Gospels reveals that the betrayal involved an intricate, time-sensitive plan.

“It was now two days before the Passover and the feast of Unleavened Bread. And the chief priests and the scribes were seeking how to arrest him by stealth, and kill him; for they said, ‘Not during the feast, lest there be a tumult of the people’” (Mark 14:1-2).

Given the Jewish way of reckoning time, and the fact Passover began at sundown on Thursday, “two days before the Passover” points to sometime during the daytime on Wednesday.

The Jewish authorities thus had a window of opportunity to arrest Jesus between Wednesday and Thursday. Beginning Friday morning, the feast of Unleavened Bread would be in full swing, and Jesus could be expected to be with the crowds during the daytime in the week-long festival.

It apparently was on this Wednesday that Judas went to the chief priests and agreed to betray him, so he “sought an opportunity to betray him to them in the absence of the multitude” (Luke 22:6). Since Judas was now serving as their spy, the Wednesday of Holy Week is often called Spy Wednesday.

Jesus being away from the crowds was important. Jesus noted that they could have arrested him any day they wanted as he taught in the temple (Matt. 26:55, Mark 14:49, Luke 22:53). By waiting until he was in a private setting, they could avoid the people rioting.

Judas did not find an opportunity to betray Jesus Wednesday night or Thursday during the daytime when Jesus was with the crowds. The next opportunity would be when he was alone with the disciples on Thursday night at the Passover meal, which would be in private.

However, there was a new complication. Jesus kept the location of the Passover meal secret until the last moment, forcing the disciples to ask, “Where will you have us go and prepare for you to eat the Passover?” (Mark 14:16).

Instead of simply telling them the location, Jesus sent two of the disciples (Luke reveals it was Peter and John; Luke 22:8) to look for a man unusually carrying a water jar, which was normally women’s work. They were then to follow this man back to a house, and there the householder would have a room prepared for them to eat the Passover meal (Mark 14:13-15).

The apparent purpose of this subterfuge was to keep the Twelve—including Judas—from knowing the location of the meal until the last moment. That way, Judas could not bring the authorities there to arrest Jesus, for he greatly desired to eat this Passover with his disciples (Luke 22:15).

At the Last Supper, Jesus announced that one of the Twelve would betray him, prompting the disciples to ask who it would be.

Jesus indicated it would be someone who dipped food in the same dish as him, which would make it obvious to anyone who was in-the-know that Judas would be the betrayer. But John’s Gospel indicates that this was a rather restricted audience. It may have only been Peter and the beloved disciple who knew.

“One of his disciples, whom Jesus loved, was reclining at table at Jesus’ side, so Simon Peter motioned to him to ask Jesus of whom he was speaking. So that disciple, leaning back against Jesus, said to him, ‘Lord, who is it?’ Jesus answered, ‘It is he to whom I will give this morsel of bread when I have dipped it.’ So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. Then after he had taken the morsel, Satan entered into him. Jesus said to him, ‘What you are going to do, do quickly.’ Now no one at the table knew why he said this to him. Some thought that, because Judas had the moneybag, Jesus was telling him, ‘Buy what we need for the feast,’ or that he should give something to the poor” (John 13:23-29) since giving to the poor was a custom on the first night of Passover.

By this point, Judas had learned what he needed to know to betray Jesus, for he had learned their plans for the remainder of the evening.

Jesus “went out with his disciples across the brook Kidron, where there was a garden, which he and his disciples entered. Now Judas, who betrayed him, also knew the place, for Jesus often met there with his disciples” (John 18:1-2).

Judas thus brought a band of soldiers and officers from the Jewish authorities to arrest him.

It was at this point that Judas betrayed Jesus with a kiss. Even though Jesus was a public figure, the guards might not know him by sight.

Also, it was dark, and they would be viewing the scene in the garden by torchlight. Even Judas himself might not recognize Jesus until getting up close to him.

By arranging the kiss, Judas apparently wanted a degree of protection. If he suddenly yelled, “This is Jesus! Grab him!” that would make it obvious to everyone that Judas had betrayed him. A melee might ensue, and Judas might be injured or killed by one of the other disciples.

But by coming up and giving the ordinary greeting gesture of a kiss, it would make the act of betrayal non-obvious. From Judas’s perspective, he might get away scot-free, with nobody realizing what he had done.

However, Jesus knew what Judas was up to. “Jesus said to him, “Judas, would you betray the Son of man with a kiss?” (Luke 22:48).

From Jesus’ perspective—as tragic as it was—everything was proceeding according to plan.
