List of former Catholics

One 2008 Pew Research Center study estimates that 10.1% of people in the United States describe themselves as former Catholics in some sense.

[1] A significant number of former Catholics join mainline Protestant denominations with a similar worship pattern, such as Lutheranism or Anglicanism, while others have become Evangelical Christians.

These people stressed they still believed in a creative power who guided the German nation and rejected atheism.

The same survey noted that some Catholics incorporate "yoga as a spiritual practice", emphasize psychics, and draw on and involve themselves in other religious movements.

[59] This section contains people who rejected Catholicism in favor of a non-religious philosophy, including atheism, agnosticism and secular humanism.
