In an interview in 2021, Arnold explained that he grew up in the Catholic Church. "I grew up Catholic, I went to church, went to Catholic school, I learned the Bible and my catechisms," the actor said in a YouTube video at the time. "And from those days I remember a phrase that is relevant today: a servant’s heart. It means serving something larger than yourself."

At the time, he was calling on elected representatives to live up to the religious teachings he had received.

"What we need right now from our elected representatives is a public servant’s heart," he said. "We need public servants that serve something larger than their own power or their own party. We need public servants who will serve higher ideals, the ideals in which this country was founded, the ideals that other countries look up to."
