How do you know that these Catholic nuns were “liberal”? I have yet to see any so-called “conservative” Catholic nun or member of the hierarchy say anything close to what this Orthodox nun has stated. Now, ask a truly Traditional Catholic nun or priest (those that believe the Catholic Faith as it was pre-Vatican II) and you’ll get the Truth.
I say the nuns that departed the lecture were liberal due to their criticism of the truth which is that Islam is at war with all non-Islams and want to dominate or kill us.
The Orthodox nun is correct. I have seen many silly liberal nuns. Some with nail polish and jewelry.
