I was listening to a Richard Ibranyi lecture last night
That's so weird. I listened to a Richard Ibranyi lecture last night also. Mine was one in which he condemned some of the Church Fathers for Hellenization. He made some good points, but by all accounts he is nuts and is not to be trusted. Believing the great apostasy started in 1033 and that there haven't been popes for almost a thousand years.
The way I understand it we are not required to correct every sin of every sinner, otherwise we would have to go up to every woman we ever meet and scold them for dressing immodestly, literally hundreds of times a day where I live. We have the obligation to correct those we have authority over, like children, spouses, servants, and those we have influence over, like friends.
