I think you're making a mountain out of a molehill here.
I don't. You may want to sweep heresy under the rug, but that's your decision.
(1) "This whole controversy" seems to exist primarily in your mind.
It only "seems" that way to you. But you're wrong.
I haven't heard anyone else complaining about it.
How many people do you need to hear from in order for what he said to be wrong?
(2) Father Barron isn't "dictating" anything (in the sense of requiring all Catholics to believe or not believe something).
He wears a collar and has a shingle. And he certainly is dictating when he speaks as a priest and states that the Ascension has "absolutely nothing" to do with what the Church teaches as a historical event.
He simply made a statement. I'm not losing any sleep over it.
But you seem to care enough to feebly defend him and put a lid on exposing his heretical beliefs. And by all means continue to sleep. Leave the rest of us who care to go about our business.
