“It is true that someone validly ordained can, for grave reasons, be discharged from the obligations and functions linked to ordination, or can be forbidden to exercise them; but he cannot become a layman again in the strict sense [cf Code of Canon Law, cann. 290-293; 1336 # 1 3, 5; 1338 # 2; Council of Trent DS 1774], because the character imprinted by ordination is for ever. The vocation and mission received on the day of his ordination mark him permanently.”
