My husband and I were Evangelical Protestant for the first 47 years of our lives.
I continue to attend Protestant worship services because I play piano and organ and am hired by these churches to provide their instrumental music.
I have no intention of renouncing the Catholic Church. My husband and I spent two years studying Catholicism before we joined RCIA (taught extremely well at our parish by ex-Evangelical Protestant pastors!), and we are convinced that the Catholic Church is the Church that Jesus founded.
For me, going to a Protestant service does nothing to hurt my faith in the Catholic Church.
What is DOES do it give me Christian friends who have the same “lifestyle” as me and my husband and do the same types of fellowship activities that we grew up with and miss terribly. For me and my husband, that means alcohol-free. We have been Catholic since 2004, and we have never become accustomed to alcohol at social gatherings, especially those gatherings in the church building itself. It’s so fun to go to a potluck or a concert that is alcohol free.
It’s not just the alcohol. There’s a READINESS among Protestants to sit down and talk about God, the Bible, current events, timely issues, struggles in our faith walk, etc. We don’t get this in the Catholic churches. What we see are people who already have friends that they’ve had since they were students and parents in the parish schools, and they on’t seem to have room for us in their lives.
Catholics admire my husband and me because we are very knowledgeable about the Bible (we can cite verses, find passages that are apropos for the situation being discussed, know the Bible stories and characters, including the Old Testament characters, and are quite fluent in Catholic apologetics. Also I play piano and organ in our Catholic parishes, and people like the “Gospel” feel that I bring to the music. (Sorry, all you Latin chant devotees!), but they also like the classical Bach that I play on the organ.
However, we don’t really have Catholic friends. We ask people out and no one is interested. I attend the Catholic Bible study and everyone is nice, but when I suggest meeting for supper before hand, or going out for dessert (not drinks) afterwards, no one is interested. My husband attend the parish Mens’ Group, and when he asks if people from his table would like to go out for coffee or lunch, no one is interested.
So for me, the Protestant churches that I play for provide that very necessary “Christian Fellowship” that so many Catholics do not understand. There is a “Catholic fellowship” of sorts, but it’s hard–I would say at this point–pretty nigh impossible–to enter into.
OP, if this is why you are attending, I understand. But if you are young, then I suggest that you immerse yourself in the activities at your Catholic parish and try very hard to learn how to make friends with Catholics. We can’t seem to do it. That’s the main reason I joined CAF–so I would have someone Catholic to talk to. My husband and I are very lonely Catholics who, after 14 years, still don’t really feel like we belong.
