My astute comments first:
I think what we see here are two things. A diocesan priest who has promised obedience to his bishop acting as a loose canon whether or not you agree with what he said in his video or at least parts of what he stated.
Secondly, you have a bishop in another state encouraging a priest in another diocese and agreeing with what he said. Bishop Strickland, though, as far as I can tell, has not criticized some of what the priest said or made clear that it was only his stance that a Catholic cannot (should not) be a democrat since it is a party that supports the massacre of unborn babies and babies born after a "botched" abortion where the baby lives, even into the final moment of pregnancy, the 9th month.
So what we have here is the bishop of the priest in question correcting one of his priests and privately now for the time being and a Bishop Strickland from Tyler, Texas supporting the same priest. This is what is so "heterodox" if you will, a bishop from another diocese interfering in the supervision of a priest who has his own bishop that he has promised obedience.
The question is, now, will Bishop Strickland be disciplined by the Pope (through the papal nuncio) and privately? Stay tuned....
