[quote=otm]Which still would have nothing to d with the validity of the Mass. As long as the priest minimally intends to do what the Church intends, the Consecration is valid. and as long as the Consecration is valid, the obligtion to attend Mass is in effect, subject only to being able to attend elsewhere.
The Church does not, and has not, taught that if a priest is in a state of mortal sin, the Mass is invalid. The priest may be guilty of another serious sin, that of sacrilege, but that does not affect the validity of the Mass.
Correct, all sacraments do not depend on the holiness of the minister. What is required is proper matter (pure wheat bread and pure grape wine), proper form (the words of institution in the context of the full liturgy), proper intention (confection of the bread ad wine) and Minister (validly ordained Bishop or priest).
