Last month Pope Francis seemed to insert his opinion into American politics and caused a bit of a stir when speaking about presidential candidate Donald Trump.

On the way home from the pope’s visit to Cuba, a reporter asked him what he thought of Mr. Trump’s idea to build a wall to keep Latin American illegal immigrants out of America. The pope responded, “a person who thinks only about building walls, wherever they may be, is not Christian.” Though the pontiff gave Trump the benefit of the doubt in that he doesn’t know all of the construction details, he also said, “but I say only that this man is not a Christian if he said things like that.”

Trump, who is never one to stifle his opinions for the sake of political correctness, said, “for a religious leader to question a person’s faith is disgraceful.”

“I am proud to be a Christian, and as president I will not allow Christianity to be consistently attacked and weakened,” said Trump.

Trump is on a serious roll that the establishment GOP is unsure whether they can stop. He certainly hasn’t let the pope’s comments weaken his campaign. In fact, Trump hasn’t really let anyone’s comments weaken his campaign, as he was the clear winner of the Super Tuesday primaries, when he won seven of the 11 primaries.

It is important to remember that while the Pope is the leader of the Catholic Church, he is human, and therefore imperfect. As a human being, he is allowed to have opinions. By being one of the first pope’s to actually voice most of his opinions, Pope Francis is making waves across the globe.

While Catholics believe in the concept of “papal infallibility,” many people, even some Catholics, do not understand what that means. A common misconception is that everything the pope says is correct or that the pope cannot sin.

Infallibility is not the absence of sin. In fact, it means what the Pope says is what the church believes, but only applies when proclaiming church doctrine. Because “Donald Trump is not Christian” is not written anywhere in church doctrine, these words, however true they may be, and not to be taken as divinely inspired or church law.

Vatican spokesman Father Federico Lombardi told Vatican Radio on Friday that the pope’s words were merely meant to express his own views that migrants should not be kept behind walls.

According to a translation from the Vatican press office, the pope talks about migration problems all over the world. Lombardi said, “It is not that the pope wishes to be, in any way, a personal attack nor an indication of voting.”

Pope Francis’ Latin title “Pontifex” literally means “bridge-builder,” so it makes sense that he would be more interested in building bridges than building walls.

Another issue some Trump supporters like to point out is that walls surround Vatican City. The Vatican does not require a separate visa or passport to enter, and walls do not enclose the entire city-state.

Today, the public is free to enter parts of Vatican City like St. Peter’s Basilica, St. Peter’s Square and the Vatican Museum using only a form of identification. It is more difficult for members of the general public to enter areas that house the day-to-day governance, but it is also difficult for the average American to enter the White House.

Although voters, especially Catholic voters, as well as presidential candidates should not take Pope Francis’ words as the words of God, his words should be at least noted since roughly one in five U.S. adults are Catholic. Pew Research Center also found that Catholics are more likely to be immigrants or children of immigrants, and 34 percent of the Catholic American population is Hispanic.
