Morality Clauses, particularly at religious institutions, are generally boiler plate. If you have scene one, you have scene them all.
The SCOTUS has already ruled on this issue. They did so 9-0. Any religious institution has the right to decide WHO is minister in that religion. A teacher, OF ANY SUBJECT, is a minister in a religious organization. Local law CAN NOT, trump the first, or any, amendment to the Constitution. The Liberals hold onto this for abortion, privacy and Miranda, even though none of these are actually in the Constitution. Not only is Religious Freedom in the Constitution, it is the #1 Amendment.
Please provide a link to one you’ve “scene”(sic) so I can verify what you claim.
