Evangelical protestants give away free bibles to people they don't know all the time, trying to save souls by convincing the person to read it, "accept Jesus", and become "born again". Trump is a well known celebrity and in the news a lot, so I wouldn't find it strange that ordinary Americans have sent him 20+ bibles in the mail over the past two decades. (the same is also probably true of people like Stephen Spielberg, Charlie Sheen, etc., etc. ...they probably get folks from the bible belt trying to "save" them by sending them stuff through the mail)
Trump, being the detached doofus he is, wouldn't bother giving away the bibles to someone who would actually use them, so he probably adds them to his vast collection and keeps them on display or in storage in some library he owns, where they collect dust. It reminds me of Clinton's visit with Pope John Paul II when the Pope was trying to discuss serious policy issues and Clinton was admiring all the Vatican artwork and trying to convince the Pope to sell him some for his private collection ("name your price").
The rest of Trump's allegedly "religious" tidbits sound pretty scripted to me, and put out there to appeal to GOP voters. I seriously doubt #1 (Trump will be a forceful advocate against Chrisitan persecution worldwide), #3 (Trump having a sincere change of heart on abortion), and #6 (Trump claims he admires Tony Perkins and Ralph Reed. Most likely he just wants their base of supporters to vote for him).
#2 may be true, but Trump is most likely a "Christmas and Easter" church goer, like a large chunk of the U.S. population. As another freeper noted, if Trump was actually a fervent church-goer, the congregation he attended would likely end up with nearly a billion dollars in offerings coming in annual, thanks to Trump's generous coffers.
I never heard that, LOL.
