What is the official Church teaching and/or guidance on attending both Mass and
a church service at another Christian denomination on Sundays? Here is some
more specific background information. My family (wife + kids) and I are
currently members of a Protestant church. I have been reading up on
the Catholic faith for a number of years now and I’m considering pursuing it
further and possibly joining the Catholic Church. However, my wife does not
share this desire.I was wondering if I could attend both on Sundays if I
became Catholic. I’m assuming that on days when our Protestant church serves
communion that I would need to refrain. I have not really brought up the issue
of the kids with my wife either, but one step at a time.
Thank you for writing! I pray that God will smooth your journey as you work your way through these issues.
You are correct that, as a Catholic, you could not receive communion in your current church since Protestant churches (unfortunately) did not retain a sacramental priesthood and therefore, apart from very exceptional circumstances, do not have the Real Presence when they celebrate the Lord’s Supper. Canon law does not allow Catholics to receive communion in these circumstances (CIC 846 §2).
Present canon law does not, however, prohibit Catholics from attending non-Catholic services. Therefore, you would be able to continue to attend Protestant services with your wife and family as long as doing so does not pose a problem for your Catholic faith.
You would have the obligations other Catholics do, such as the duty to attend Mass. In some mixed-marriage families this is solved by attending Mass on Saturday evening and then going to Protestant services on Sunday morning, or the reverse, or by going to both services on Sundays (e.g., a morning service at once church and an evening service at the other). In some cases, both spouses go to both services.
Hope this helps, and God bless you!
