And of course, as we’ve seen, it becomes a REALLY big deal when it’s LUTHER that Catholics are denigrating.
Then one man invalidates all of Protestantism.
The double standard applied is truly staggering.
Insofar as Luther the man is concerned at issue is how Luther's scrupulosity, a psychological disorder, informed the development of reformed doctrine. Catholics are not concerned with Luther's impeccability or lack thereof. Luther himself held the position of Catholics:
"The Church cannot err in proclaiming the faith. Only the individual within her is liable to error." ~ Martin Luther
As an aside, I would recommend watching this video by Father Barron on the Council of Trent, the Church's response to the Reformation. I think you might be surprised.
If it wasn’t for double standards, they’d have no standards at all! ;o)
