As perhaps one of the most powerful and influential Christian fundamentalists in U.S. history, Vice President Mike Pence has made no secret about his mission to uphold stringent religious values in the country.

At the World Summit in Defense of Persecuted Christians on Thursday, Pence used religion as a way to present the Trump administration’s worldview, specifically on how Christians are “under siege, particularly by ISIS and radical Islamic terrorists.” In a White House article published by Pence this week, he wrote that his presence at the summit, organized by the Billy Graham Evangelistic Association, “reaffirmed the president’s commitment to defending Christians and, frankly, all who suffer for their beliefs across the wider world.”

Long before hitching his future to President Donald Trump, Pence’s religion has made up a significant part of his political identity. He was born Catholic but adopted evangelicalism in college after attending a Christian music festival in Kentucky. Ever since, the former Indiana governor has consistently introduced himself as “a Christian, a conservative, and a Republican, in that order.”

And he hasn’t been afraid to talk about his faith and the beliefs that come along with it, receiving both praise and criticism. Here are some of the more powerful lines Pence has spoken on religion during the course of his political career.

Many Americans recall their college years as a formative period characterized by learning, friendship, and in some cases, a little too much partying. While Pence likely had a similar experience, perhaps sans the partying, at Hanover College, he’s recalled college as the time of his spiritual awakening.

Delivering the commencement speech at his alma mater in 2008, Pence told the crowd about the best friend he made before he graduated in 1981. His name, he said, was Jesus Christ, and he had a much more profound impact on the future vice president than did his degree in history.

From the time he entered politics, Pence has been a prominent voice in the anti-abortion movement. In March 2016, then-Gov. Pence made Indiana’s draconian abortion laws even more stringent, banning women from seeking abortions because their fetus has a disability.

In July 2016, Pence returned to his favorite issue, signing an Indiana law that required people to hold funerals for aborted fetuses. And since he’s become vice president, he’s continued to push for an end to abortion.

As both an Indiana congressman and governor, Pence did everything in his power to weaken institutions, such as Planned Parenthood, in order to prevent Hoosiers from having access to abortions. But in his new role, he has the power to expand his influence across the country.

Just a week after he was sworn in for his new job in January, Pence became the first sitting vice president to address the crowd at the March For Life, the annual anti-abortion gathering in Washington, D.C. Pence assured the crowd that Trump would cut off federal funding for abortion providers, and insinuated that the president’s pick for the Supreme Court, later revealed to be Judge Neil Gorsuch, would help overturn Roe v. Wade, the landmark abortion case.

In March, Pence affirmed Trump’s desire to move Israel’s U.S. embassy from Tel Aviv to Jerusalem, a move favored by both fundamentalist Christians and hard-line Jews alike. Many fundamentalist Christians support the Jewish State because they view the return of Jews to Israel as the fulfillment of biblical prophecy. Yet, Palestinians have been vocal in their pleading to Trump, Pence and the rest of the administration to not make such a move.
