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.
The study estimated Christianity was the largest faith at 2.2 billion adherents or 31.5 percent of the world's population. The Roman Catholic Church makes up 50 percent of that total, with Protestants -- including Anglicans and non-denominational churches -- at 37 percent and Orthodox at 12 percent.
