A Jesuit preparatory school in Indiana has refused to fire a teacher who is in a same-sex marriage, prompting the Archdiocese of Indianapolis to say that it would break its ties with the school, officials said Thursday.

Brebeuf Jesuit Preparatory School learned recently that the archbishop of Indianapolis, Charles C. Thompson, would issue a decree on Friday stating that the school would no longer be recognized as a Catholic school by the archdiocese.

Brebeuf, an independent Catholic school in Indianapolis founded in 1962, has been at odds with the archdiocese since learning about two years ago that a longtime teacher at the school had married someone of the same sex.

The school was asked verbally at the time by the archdiocese not to renew the teacher’s contract because the teacher’s marital status did not conform with church doctrine, according to a letter issued Thursday to Jesuits in the Midwest by the USA Midwest Province of the Society of Jesus. (The Roman Catholic Church does not recognize same-sex marriages.)
