An on-campus Catholic group was suspended at Harvard after asking one of their leaders to step down because she was a lesbian.

Harvard College Faith and Action asked the unnamed woman to step down in Sept. 2017, according to student newspaper the Harvard Crimson. The Office of Student Life said the group’s suspension lasts for one year.

“HCFA had conducted itself in a manner grossly inconsistent with the expectations clearly outlined in the Student Organization Resource and Policy Guide,” university spokesperson Aaron M. Goldman wrote in a statement.

Harvard College Faith and Action leadership deny that they violated Harvard’s student organization policies.

“We reject any notion that we discriminate on the basis of sexual orientation in our fellowship,” HCFA co-presidents Scott Ely and Molly L. Richmond wrote in an email. “The student in this case was removed because of an irreconcilable theological disagreement pertaining to our character standards.”
