[quote=Paris Blues]I know that it’s a MUST to go to Mass if you’re a confirmed Catholic and it would be a mortal sin to miss Mass just for no reason.
Now, what happens, if after I get confirmed, that my parents invite me to go to their church? Would I have to go Mass Saturday night then go with them Sunday? How would this work yet I don’t want to be rude to my parents?
Hi Paris Blues,
Congratulations on your upcoming confirmation to the Catholic Faith! I have pasted below the response to your question from a Catholic website. Hopefully it provides the answer you are seeking.
Catholic Article - May a Catholic attend a service at a Protestant church?
Issue: May a Catholic attend a service at a Protestant church? How may a Catholic participate?
Response: A Catholic may attend and participate in common prayer at services in Protestant churches. Catholics are encouraged to pray and sing, and they may read or preach, but a Catholic may not receive “communion” if this is part of the service.
Discussion: There is no ban against a Catholic attending a Protestant service, although a Catholic may not receive “communion” if made available. This is largely a consequence of the invalid ordination of ministers attempting to confect the Sacrament. Canon 844 of the Code of Canon Law says that Catholic members of the Christian faithful may receive sacraments only from Catholic ministers. Further, the Catechism of the Catholic Church explains that there can be no “Eucharistic intercommunion” between the Church and Protestant communities (no. 1400).
Participation in common prayer without taking part in a communion rite is an act of true ecumenism—promoting unity without denying the truths of the one true faith—and should not likely be a cause of scandal. The Pontifical Council for Promoting Christian Unity, in its 1993 Directory for the Application of Principles and Norms on Ecumenism, encourages such participation:
In liturgical celebrations taking place in other churches and ecclesial communities, Catholics are encouraged to take part in the psalms, responses, hymns and common actions of the church in which they are guests. If invited by their hosts, they may read a lesson or preach (no. 118).
However, the Catholic must not think of the worship service as an addition or substitution for Mass. It is important that the Catholic does not give the impression that there is no real separation between Catholics and Protestants. Protestant services must not be attended in order for the Catholic to experience “feelings” of fellowship or closeness to God.
