For over 25 yrs. I taught in Catholic schools, mostly in Theology, so I am well aware of the required oath taken by teachers.  However, you still have not provided any proof that Ms. Weiss was teaching (in her Literature classes for 11 yrs.) anything contrary to authentic Catholic doctrine or teaching.  Since you were not at ND to hear Ms. Weiss lecture I am sure you must have sat in her classes. Right?
