Yes, ..but that was his mother's faith...I've seen no evidence he's ever attended church outside of a Holiday....it's just not part of the Trump Empire.
He knows he cannot win without the Christian community....so he set the stage several times to "show" that he is by gathering some Christians to pray for him in a photo shoot..and waving the Bible his mother gave him.
When he's been interviewed his responses are what you would hear from a child....and when he was called on those he then resorted to simply "not wanting to get into details" as he said.
It's not unusual for people to question what he says as he's so often wrong or exaggerates, as well as lies....but he's a master at "coloring" not just his stage presence but what he says as well......for every oops! there's a tango step he'll use to untwist his feet.
I would have much better accepted the guy if he just remained neutral about matters of the faith.....but his "show", which is deceptive, puts him in another category altogether.
“Thou shalt not lie...”. WOOPS!
