“VATICAN CITY, June 23 (Reuters) - The Vatican on Tuesday reaffirmed a long-standing rule that only an ordained priest or deacon can give a sermon at a Catholic mass, rejecting a request from German bishops to broaden the practice and allow sermons by women or other laypeople.”
So by the logic that only men can preach because Jesus was a man, do you also enforce the rule that only middle Eastern Jewish carpenters can preach?
If not, then it is clearly possible for people to “stand in” for Jesus when preaching, even without matching his characteristics perfectly. The decision to specifically exclude women based on that one particular characteristic is therefore obviously sexist.
