I have been wondering recently who exactly is the One, Holy, Catholic, and Apostolic Church? Coming from the Roman Catholic tradition, they claim to be the one church and everyone else is not. Well, they say if you are baptised, you are in the church but not fully. So, I was wondering which churches have the marks of THE Church. Is it all people who have been validly baptised? I apologise if this post isn't supposed to go in here. I didn't know if I should put it in here or in the Theology section.
