This was an interesting video clip on the PNCC. They have valid sacraments and can receive communion at the Catholic Church (ie Roman). If I recall at one point the PNCC was in communion with the Anglican Communion but broke ties over issues like womens ordination.
From their web site and for obvious reasons they seem to be concentrated in the Eastern US. I imagine they could do somewhat better if they dropped the Polish (mentioned in the news article) but then again maybe not. That is their unique identity.
Has anyone any experince with them?
