You can get excommunicated for being too much of a dick or being too accepting.
According to the article he was excommunicated
because of his public teaching on the ordination of women contrary to the teaching of the Church and his public celebration of the Eucharist when he did not hold faculties to act publicly as a priest.
Note two things:
1)
Public teaching. The Church doesn't care that he supports the ordination of women privately, hell, it probably doesn't even care that he shares these views - it objects to one of its priests teaching (as a
priest, not as some random guy!) that the Church is in the wrong.
2) He celebrated the Eucharist (ie held Mass) when he did not have authorization to do so. This is an
incredibly grave offense - kinda like General Ripper ordering Wing Attack Plan R against the explicit wishes of the President. If he really did this, there's no way around his excummunication.
Oh, and later in the article there's this:
He has even reportedly presided at same-sex ceremonies.
Yeah, this isn't just some guy being subjected to a witch-hunt for his deeply-held convictions. This guy had it coming.
EDIT: It just gets better and better:
Australian media also reported that in August 2012 he was present at a Mass where a dog had received Communion, which Fr Reynolds said he was not aware of until after the incident.
That month Archbishop Hart wrote to him warning that if he continued to act publicly as a priest he would “be forced to take further canonical action for the good of the Church”.
Yeah, I'm pro-same sex marriage, I'm pro-ordination of women, I'm as progressive as Catholicism gets, but to this guy I say: Good riddance.
