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.
For many, Catholicism and Christianity are one and the same, but they are quite different. This common mistake comes from the fact that Catholicism is part of Christianity, but Christianity is a very broad term that encompasses many beliefs and dogmas, resulting in different denominations of Christians.
