Trump has made several statements about his faith, some of which are summarized below:
Mr. Trump says he is Presbyterian. There is a movement in the Presbyterian church to have him kicked out although the Presbyterian headquarters has been unable to find which church he is a member of. The Presbyterian church has also sent him a letter essentially admonishing him for his statements on immigration.
This is how he describes receiving Holy Communion:
"When I drink my little wine — which is about the only wine I drink — and have my little cracker, I guess that is a form of asking for forgiveness, and I do that as often as possible because I feel cleansed,” he said. “I think in terms of ‘let’s go on and let’s make it right.’"
When attending church just prior to the Iowa caucus, Trump mistakenly tried to donate money by putting it on the silver plate used for communion.
Trump claims to read the Bible, but has declined to name his favorite passage. He has stated that his Art of the Deal is second only to the Bible.
During the Iowa primary, he displayed the Bible given to him by his mother as part of his pitch to evangelicals.
When making a speech at Liberty University, Trump read a passage from the Bible, desribing it as "Two Corinthians" instead of the more customary "Second Corinthians."
