If you're looking for the church that is closest to the Catholic Church in terms of doctrine and practice, that would be the Eastern Orthodox churches. Even the Lutherans are far closer to the Catholic Church than the Methodists.
Catholics, Anglicans, and Protestants are all Christians. Catholics believe in the Roman Catholic Church and the Pope. Protestants believe in the lack of a single leader of their church. Anglicans believe in the Church of England.
