Speaking with reporters Thursday, Pope Francis criticized Donald Trump’s rhetoric and even challenged his faith. “A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian,” Francis said, adding he wasn’t sure if Trump had actually expressed that kind of rhetoric.

On the policy question, the pope is just plain wrong. If our nation doesn’t enforce its borders, it will cease to be a nation — regardless of what a Marxist pope may say. He invoked the “Golden Rule,” but while that’s great for interpersonal relationships, it’s a deadly immigration policy.

As for the faith question, Trump might have simply thanked the pontiff for helping him win votes in Evangelical South Carolina. Instead, Trump issued a statement firing back at the pope. “For a religious leader to question a person’s faith is disgraceful,” Trump said. “I am proud to be a Christian and as President I will not allow Christianity to be consistently attacked and weakened, unlike what is happening now, with our current President.”

Never mind the spectacle of the Catholic leader challenging a (self-proclaimed) Presbyterian. There have been more than a few disagreements about that over the years…

But in all fairness, the thin-skinned wanna-be Constantine-in-chief has a questionable track record with Christianity. You will know him by his fruits. The man wrote a book on how to screw people in business. And while he says it’s the second-best book in the world after the Bible (nice humility there), when Trump was asked his favorite passage from the Bible, he couldn’t name one. Most importantly, Trump boasts that he never asks forgiveness from his Creator, revealing that he either misunderstands Christianity entirely or rejects its tenets.

What’s perhaps most fascinating, though, is that Trump is so narcissistic that he believes whatever he says today trumps what he was actually recorded as saying previously. Less than a week ago, he wondered, “How can Ted Cruz be an evangelical Christian when he lies so much and is so dishonest?” He has also questioned Ben Carson’s faith. Could it be that Trump’s true religion is uniquely Trump-based?
