Hm! I'd like to get beyond the Protestant/Catholic thing. I have kinfolk on both sides and we get along well because we discuss rather than argue.
As for me, I'm a 'big tent Christian'. I presume to strict Catholics that would make me a Protestant, but many Protestants would not accept me as one of theirs.
Here are a few 'beliefs'.
(1) None of us knows very much about eternal mysteries. I can live with that. "Someday He'll make it plain to me" - an old gospel hymn. Or, "Farther along we'll know all about it" - another old hymn whose opening words reflect my thinking
(2) Jesus is my Lord. Now this doesn't mean that Jews, Muslims, Buddhists etc can't get to heaven. I honestly believe that there are different paths that we need to respect. I'm not arrogant enough to believe that God chose me, or that I'm smart enough, to be a Christian while others are destined for hell. (By the way, I don't suscribe to most traditions re hell.)
(3) The church can serve as a fine institution - extended family, a source of morality, etc. - unless it begins to control our minds or create hatred. How many wars in the past have been caused by religion - and yes, obviously today as well?
(4) When Jesus was asked by the lawyer how to inherit eternal life, he didn't respond with any narrow doctrines. No, he gave the parable of the Good Samaritan, a person not of the same faith as the Jewish traveler. Says something about the need for tolerance.
I've rambled on enough. As far as choosing a local church, I look for an interesting service, good and intelligent preaching, an open-minded congregation, and a friendly bunch. The label means little to me. Depends on the local church. I am likely to find what I'm looking for (oh, and I'm not into high liturgy) among UCC, Methodists, Presbyterians, Disciples, and 'ABC' Baptists, though other churches might be okay depending....
