I believe in the holy catholic church, the communion of the saints

First, understand that "catholic" is an old word meaning "universal". No one is pledging allegiance to the Church of Rome by repeating the Apostles' Creed.

The Church consists of followers of Christ in every place and every time. It is the universal community of saints, "saints" being another name for Christians in the New Testament.

The Church is not a place you go. It's not an institution founded by people. It isn't even synonymous with any denomination or sect. Simply put, it's all people throughout all time and space who love Jesus Christ and are loved by him.
