The Justice Department today filed a Statement of Interest explaining that the First Amendment protects the right of the Roman Catholic Archdiocese of Indianapolis to interpret and apply Catholic doctrine. The lawsuit was brought against the Archdiocese by a former teacher who was fired from a Catholic high school within the diocese because he was in a same-sex marriage in contradiction to Catholic teaching on marriage. The Archdiocese indicated that the school had to terminate the teacher, or the school would forfeit its Catholic identity, which would have led to several repercussions for the school.
