Are there any new heresies?

This post by Father Z suggests that the modern "old school" nun of the LCWR have simply re-invented the heresy of Montanism - the notion that the Holy Spirit speaks directly to prophetesses - in order to to circumvent orthodox Catholic teachings:

Why is Florence Deacon saying this? She is manifesting yet another dimension of the Magisterium of Nuns.

She is using the “poor”, and the poor can be translated loosely, as a hermeneutic for just about everything they want to justify doing. La Voz de los Pobres, The Voice of the Poor (it’s just better in Spanish), is a cover for setting aside Magisterial teaching.

This is how this works.

First, I take the “experience” of the person I am talking to. That person, who has some sort of conflict or problem, is in the category of “the poor”, or “the marginalized”, no matter what their income is. When that “poor” person speaks, I am listening to the voice of God, because the voice of God is heard in La Voz de los Pobres. So, the “poor” person’s experience, and then my “experience” of listening, become the grounding of interpretation of God’s will. See?

Then, after this listening, I interpret what the person wants to do. For example, the “poor” person wants to have sex with someone of the same sex, or wants to simulate ordination to the priesthood, or wants to vote for pro-abortion politicians who support certain social justice programs, or even wants to have an abortion.

Then, because the “poor” person told me what they want, and because I, the interpreter of La Voz de los Pobres have listened, I give the “poor” permission to do what they want. I have effectively bypassed the Church and the authentic Magisterium. I, wielding the Holy Spirit, have listened to God in La Voz de los Pobres and that listening has given me all the authority I need no matter what the “official” Church says.

Say for the sake of this exercise I am a LCWR nun. I encounter another “gay” person. I listen. I can now affirm her in her “gayness”. I can affirm her because I listened to the voice of God in La Voz de los Pobres.

This blah blah from Sr. Deacon, reveals what these nuns are after: they seek to set aside the defined teaching of the Church and simply affirm their own desires. They are seeking to supersede the Magisterium of the Pope and bishops with their own Magisterium of Nuns, rooted in whatever the hell they want to do.
