InterVarsity Christian Fellowship USA, which operates programs at 667 college campuses, has confirmed plans to fire any staff members who support same-sex marriage, Time reported. The dismissals will start next month and the organization has asked those who back same-sex marriage to come forward and identify themselves. The news comes as about 10 staff members formed a group to speak out on behalf of their gay and lesbian students.

Bianca Louie, who until recently worked for InterVarsity at Mills College, said she feared the policy would endanger work that the group does. “I don’t know how InterVarsity can do ministry on campus with integrity anymore,” Louie said. “Mills is a women’s college with inclusive trans policies, and higher ed is overall making more efforts to be inclusive and safe for LGBTQ students. … I could see us getting kicked off campus because of this.”
