Tony Perkins, president of anti-LGBTQ group Family Research Council and radio host, advised yesterday that Christians “bear in mind” the “biblical truth” that marriage is between a man and woman before attending the wedding of a gay couple.

Yesterday, the day before lawyers delivered arguments in the Supreme Court case Masterpiece Cakeshop v. Civil Rights Commission, which could set a legal precedent regarding whether businesses can deny services to patrons based on their sexual orientation, Perkins answered calls from listeners and discussed the significance of the case. One caller asked whether it was imperative that Christians do not attend same-sex weddings or if Christians should be compassionate toward gay people.

“I get the whole argument about love—‘we just need to show love.’ Sometimes expressing love is standing for truth, and I think we could lull people into a false sense of security by simply going along with what is culturally acceptable in some circles,” Perkins said.

He continued, “Now, I’m not going to tell people across the board you shouldn’t go. I haven’t gone that far. I would tell people to be very prayerful about it, but I personally—it’s not something I could do. I don’t think it would be a good representation, people knowing very clearly my stand on biblical truth, and I think other Christians need to bear that in mind as well.”
