Really? I didn’t realize the Catholic Church took this position with priests. Well, maybe there’s a nice parish in Uzbekistan, or Siberia, or somewhere near the Arctic Circle...
send him to mugabe’s land and let him act black there and lets see what happens to him there
The theology is that the Sacrament of Orders imparts an "indelible mark" on the recipient. That is the reason that you never hear of one being defrocked. (The technical term is laicized, by the way -- even though the Church has removed their right to function as a priest, they are still technically and sacramentally priests). In fact, that is the reason why an ordinand (an ordained deacon, priest, or bishop), even if married at the time of his ordination, may never be married after ordination (that applies to both the Latin and Eastern rites -- to include the Orthodox Churches).
So, in theory, they could suspend him from ministry. They could laicize him (prohibit him permanently from exercising any ministry, wearing clerical clothing, and identifying himself as a priest), but he will always and forever be, at least technically, a priest.
