Wait a second... They are being ordained by AMERICAN bishops? Umm, doesn't that make their ordination, although unwise and probably impious, 100% valid?
The article is about a priest who was ordained by a pretender bishop. (Shall I coin the term, anti-bishop?) That is an horrific offense against the faith of the poor congregants. Add to that the lies to make them appear legitimate, and the crime, if true as alleged, is unspeakably demonic. But you are talking about something far less grave.
Unfortunately I have not at my fingertips names, numbers, nor embarrassing photos.
For a a man to be validly ordained a priest, he must affirm his beliefs in all of the truths of the Catholic faith (including the powers and priviledges of the papacy), must swear to teach them, and to be bound by the authority of the legitimate heirarchy of the church.
So if your Chinese "priest" does not believe in or intend to teach all of the truths of the faith, and does not hold any belief in the authority of Peter, nor intend to be subject to him, and to a valid and licit Bishop......he cannot be a priest, because he is lying to God.
So, he is as much a real priest as a practicing homosexual. Both have sought ordination under false pretenses.
