Why Was Arius a Heretic?

Erick Thomas Ybarra writes:

Jimmy Akin’s argument here on the doctrine of Justification is right on the money, and it is why I wish the authors of the Open Letter did not write on this point. It is very clear Amoris dodges this accusation. . . .

My concern, however, with Akin’s article, and I would ask him to clarify for me, is that his argument on the “canonical crime of heresy” vis-a-vis the definition of dogma which requires both divine & catholic faith, would render the ancient presbyter Arius as free of the canonical crime of heresy.

The Council of Nicaea (325) gives us the Creed with “homoousian” (one substance), but only anathematizes those who hold to it, and does not specify anywhere in clear enough terms that the matter is “divinely revealed”.

Happy to oblige!

The reason that Arius counts as a heretic can be answered in more than one way.

 

By Historical Standards

The first way involves judging him by the standards of his own time. In this era, the term “heresy” did not have its modern, technical meaning.

Instead, as I discuss here, it was used in a broader sense that could refer to anything that conflicted with basic Christian doctrine or practice.

Consequently, it was not necessary at that time to show that a particular doctrine had been infallibly defined as divinely revealed to label someone a heretic.

Arius’s denial of the divinity of Christ unambiguously conflicted with basic Christian teaching, as solemnly confirmed by the First Council of Nicaea, and so he was labelled a heretic.

Thus, Arius has been known as a heretic down through history.

 

By Modern Standards

A second way of approaching the question is to apply the standards of our time, retrospectively, to the case of Arius. In other words: Would he be convictable as a heretic given the modern use of the term?

Today the term heresy, in simple language, refers to the obstinate, post-baptismal refusal to believe a dogma (for the technical definition, see CIC 751 with CIC 750).

Arius certainly was obstinate at the Council of Nicaea. He refused to submit to its teaching on the divinity of Christ and was consequently sent into exile. He also was baptized.

This leaves us with the question of whether the divinity of Christ is a dogma—that is, a truth that the Magisterium has infallibly defined to be divinely revealed.

There are several issues to be considered here:

  1. What the Council of Nicaea actually said
  2. What authority the Council was understood to have at the time
  3. What authority it is understood to have today

 

What Nicaea Said

Regarding the first question, the Council published what scholars refer to as the Creed of Nicaea. It was later supplemented at the First Council of Constantinople (381) to for the Niceno-Constantinopolitan Creed (more popularly called the “Nicene” Creed).

The main difference between the two creeds is that the Creed of Nicaea did not end the same way. It didn’t have the passage declaring the divinity of the Holy Spirit. Instead, it ended this way:

[We believe . . .] in the Holy Spirit.

However, those who say: “There was a time when he [the Son] was not” and “Before he was born he was not” and that he was made from nothing or who say that the Son of God may be of a different hypostasis or essence, or may be created or subject to change and alteration, [such persons] the Catholic Church anathematizes (DH 126).

As Erick points out, the anathema at the end of the Creed does not mention the doctrine being divinely revealed.

However, another part of the Creed indicates that divine revelation is involved. The Creed begins:

We believe in one God, the Father almighty, creator of all things, visible and invisible, and in one Lord Jesus Christ, the Son of God, the Only-Begotten gener­ated from the Father, that is, from the being of the Father, God from God, light from light, true God from true God, begotten, not made, one in being with [homoousion] the Father, through whom all things were made, those in heaven and those on earth . . . (DH 125).

The key part of this for our purposes is the verb that introduces and governs the entire sentence: “We believe” (Greek, pisteuomen, Latin, credimus).

This verb indicates that the truths articulated belong to the Faith (Greek, hê pistis, Latin, fides), and thus as belonging to divine revelation.

We thus have the text of Nicaea indicating that divine revelation is involved.

 

What Authority the Council Was Understood to Have at the Time

The First Council of Nicaea was initially confirmed by the authority of the Emperor Constantine. Bishop Karl Josef von Hefele notes:

Constantine the Great solemnly confirmed the Nicene Creed immediately after it had been drawn up by the Council, and he threatened such as would not subscribe it with exile. At the conclusion of the Synod he raised all the decrees of the assembly to the position of laws of the empire; declared them to be divinely inspired; and in several edicts still partially extant, he required that they should be most faithfully observed by all his subjects (A History of the Councils of the Church, I:42).

This is interesting from the point of view of history, but the question from a theological perspective is what the pope said about the Council. According to von Hefele:

The signatures of the Pope’s legates, Hosius, Vitus, and Vincentius, subscribed to the acts of the Council before the other bishops, must be regarded as a sanction from the See of Rome to the decrees of Nicaea. Five documents, dating from the fifth century, mention, besides, a solemn approval of the acts of the Council of Nicaea, given by Pope Sylvester and a Roman synod of 275 bishops. It is granted that these documents are not authentic, as we shall show in the history of the Council of Nicaea; but we nevertheless consider it very probable that the Council of Nicaea was recognized and approved by an especial act of Pope Sylvester, and not merely by the signature of his legates, for the following reasons:—

It is undeniable, as we shall presently see, that

α. The fourth ecumenical council looked upon the papal confirmation as absolutely necessary for ensuring the validity of the decrees of the Council; and there is no good ground for maintaining that this was a new principle, and one which was not known and recognized at the time of the Nicene Council.

β. Again, in 485, a synod, composed of above forty bishops from different parts of Italy, was quite unanimous in asserting, in opposition to the Greeks, that the three hundred and eighteen bishops of Nicaea had their decisions confirmed by the authority of the holy Roman Church (confirmationem rerum atque auctoritatem sanctae Romanae Ecclesiae detulerunt).

γ. Pope Julius I [r. 337-352] in the same way declared, a few years after the close of the Council of Nicaea, that ecclesiastical decrees (the decisions of synods) ought not to be published without the consent of the Bishop of Rome, and that this is a rule and a law of the Church.

δ. Dionysius the Less also maintained that the decisions of the Council of Nicaea were sent to Rome for approval; and it is not improbable that it was the general opinion upon this point which contributed to produce those spurious documents which we possess (ibid. I:44-45).

At this time, the theology of ecumenical councils and when they teach infallibly had not been worked out. That was a subject that would be clarified through later doctrinal development. However, Nicaea was held by its supporters to be divinely guided and supremely authoritative. (The Arians, naturally, disagreed.)

 

What Authority the Council Is Understood to Have Today

Now that the theology of ecumenical councils has undergone a high degree of doctrinal development, how is First Nicaea viewed from a contemporary perspective?

It is universally regarded as the first of the ecumenical councils. According to Church teaching:

The college of bishops exercises power over the universal Church in a solemn manner in an ecumenical council. But there never is an ecumenical council which is not confirmed or at least recognized as such by Peter’s successor (CCC 884).

Bishop von Hefele argues that First Nicaea was recognized as ecumenical by a special act of Pope Sylvester I (r. 314-335), during whose reign it occurred.

However, even if it turned out that Pope Sylvester did not recognize it by a special act, the council would still be ecumenical.

A special act of recognition by the pope is not required—only the recognition itself. Subsequent popes—including all of the recent ones—have unmistakably recognized this council as ecumenical, and so it is.

 

Prosecuting Arius for Heresy by Modern Standards

That brings us to the Creed of Nicaea’s infallibility. While the theology of magisterial infallibility also had not been developed at the time the Council met, it has now, and the Church holds that:

[When the bishops are] gathered together in an ecumenical council, they are teachers and judges of faith and morals for the universal Church, whose definitions must be adhered to with the submission of faith (Lumen Gentium 25).

At Nicaea, the bishops were gathered in an ecumenical council, so that leaves us with the question of whether the Creed of Nicaea counted as a definition—that is, as a statement the bishops intended to be binding on all the faithful and to absolutely bring all legitimate discussion of a matter to an end.

Note that an ecumenical council—like a pope—does not have to use any set form of words to issue a definition. It does not have to say “anathema” or “we define.” It just has to indicate in one way or another that the matter is definitively settled.

In this case, it did. The bishops of the Council of Nicaea clearly intended to bring all legitimate discussion of the topic to an end, for all of the faithful, and to make this point they put their teaching in the form of a profession of faith for the faithful to say.

This profession of faith also has become universal in both East and West as an obligatory expression of Christian truth. One cannot be an orthodox Christian and deny it. (This means, among other things, that the ordinary and universal magisterium also has infallibly taught it, not just the extraordinary magisterium.)

That brings us to the final issue, which is whether the use of the verb “believe” (pisteuomen/credimus) indicates a matter of divine revelation.

It does. In the Doctrinal Commentary on the Concluding Formula of the Professio Fidei, Ratzinger and Bertone note that the verb “believe” (Latin, credo) is used for “all those doctrines of divine and Catholic faith which the Church proposes as divinely and formally revealed and, as such, as irreformable” (n. 5).

By contrast, the verbs “accept and hold” (Latin, amplector ac retineo) are used for “all those teachings belonging to the dogmatic or moral area, which are necessary for faithfully keeping and expounding the deposit of faith, even if they have not been proposed by the Magisterium of the Church as formally revealed” (n. 6).

Such a truth is thus a “sententia definitive tenenda” (Latin, “opinion to be definitively held”—as opposed to be believed with divine and Catholic faith).

Thus, from a modern perspective, the confession of faith offered in the Creed of Nicaea—or the modern Nicene Creed—consists of matters to be believed, not merely held, and thus as consisting of truths contained in divine revelation.

Consequently, Ratzinger and Bertone state that among truths of this kind “belong the articles of faith of the Creed, the various Christological dogmas and Marian dogmas” (n. 11).

By requiring Christians to profess belief in the divinity of Christ, Nicaea thus infallibly defined that this is a truth of divine revelation.

Therefore, even when we apply modern criteria, Arius was a heretic.
