He is most certainly not a Christian, devout or otherwise.
... neither adulterers, nor effeminate, nor abusers of themselves with mankind ... shall inherit the kingdom of God.

And why did Thiel's boyfriend, with whom he was cheating on his so-called spouse, die just like all the people die who cross Vladimir Putin? On which see below.
Meanwhile The Week here adds to this decidedly not Christian horror show by quoting a fornicating Episcopal priest who has the gall to call Thiel . . . heretical!
As an Episcopal priest, “I find Thiel’s warnings heretical,” said Kevin Deal in the San Francisco Standard. In the Bible, the Antichrist represents “a foil to Christ,” not “a tool to sow fear or division.” Thiel is cynically weaponizing “the language of faith” to serve his own ends.
Mr. Deal, formerly Mr. Neil, adopted his girlfriend's surname when they married after living together for over a year, including while at seminary. They were married, of course, by a female Episcopal priest. All of which was celebrated, of course, by The New York Times.
Thiel is heretical to these people because he is Republican, not because he is a faggot.

If you're looking for the Antichrist, look no further than these principals. Neither shall they say, Lo here! or, lo there! for, behold, the antichrist is in your midst.
