Strange that with respect to anything traditional Catholic post-conciliar hypocrites lose their usual manners and forget about "imperfect communion" or brothers/sisters in less than full unity.
Logically, assuming hypothetically as truth revolutionary premises of post-conciliarists these sisters should be placed in a higher degree of communion with them than pastors and "orthodox" clergy they meet and flatter in their dialogue, and do not dare to call those pastors and clergy "schismatics".
Because the Church is in free fall, chaos and confusion I believe these nuns are doing the best they can. They are not theologians, but are praying and not rioting, and it appears their congregation is growing.
