Address him with proper respect, vile scuм. That's Archbishop Thuc to you, lead prelate of his country, having earned three advanced degrees from Rome, charged with founding and running seminaries, and in fact given a Pontifical Mandate to consecrate bishops as he felt necessary. Due to his experience founding seminaries, Archbishop Lefebvre had initially asked +Thuc to set up Econe, but he declined, believing that at his age he did not have the energy to pull it off.
I would ban your filthy ass just for derisively referring to him as "Thuc". If you wish to respectfully disagree with him, you're entitled, since he wasn't infallible, and if you have actual rational points to make regarding the validity of the Holy Orders, by all means so so ... but you've done nothing but slander the man with trash, and you will pay for it next to +Kelly in Purgatory, the guy who came up with most of this filth because he didn't want to lose too much collection-basket revenue to CMRI and other chapels from the lineage of the Archbishop.
As for what you derisively refer to as "superpowers", Pope Pius XI granted him a "Mandatum" to consecrate bishhops as he saw fit without getting prior approval from Rome due to the fact that he was in a hostile region of the world under threat from Communists, something which both Pius XI and Pius XII did on a regular basis, and on those other occasions when they did so, they commanded that the prelate keep his own episcopal orders under wraps (some of them revealing it only later) and also to keep secret the consecrations they performed ... i.e. no witnesses despite the maniacal ravings of Father Clarence Kelly. Pope Pius XII renewed the mandate.
As for his not having mentioned it, he didn't mention a lot of things and did in fact in humility gratefully accept a position as an assistant in a diocese helping give catechism for children, hearing confessions (with lines out the door), and never once known to have uttered a peep of complain about living in a dirty little Rome not fit for an assistant pastor, much less a bishop. There's a copy of the docuмent out there. And what's it to you whether he even had one, since +Lefebvre did not.
