A Texas law professor and her wife tried becoming foster parents for refugee children, but a Catholic child welfare charity turned them away because the lesbian couple didn’t “mirror the Holy Family,” said a new lawsuit.

Fatma Marouf, a professor at Texas A&M University School of Law, and her wife Bryn Esplin, a Texas A&M bioethics professor, were married in 2015 and attempted unsuccessfully to have a child through reproductive technology, their lawsuit said. They became interested in becoming foster parents for a refugee child and went through an application process with Catholic Charities of Fort Worth—an agency that Marouf knew about through her immigration law work as director of Texas A&M’s Immigrant Rights Clinic.
