Whether the mass of a sinful priest is of less worth than the mass of a good priest?

❌ Objection 1 : It seems that the mass of a sinful priest is not of less worth than that of a good priest. For Pope Gregory says in the Register: "Alas, into what a great snare they fall who believe that the Divine and hidden mysteries can be sanctified more by some than by others; since it is the one and the same Holy Ghost Who hallows those mysteries in a hidden and invisible manner." But these hidden mysteries are celebrated in the mass. Therefore the mass of a sinful priest is not of less value than the mass of a good priest.

❌ Objection 2 : Further, as Baptism is conferred by a minister through the power of Christ Who baptizes, so likewise this sacrament is consecrated in the person of Christ. But Baptism is no better when conferred by a better priest, as was said above (Question [64], Article [1], ad 2). Therefore neither is a mass the better, which is celebrated by a better priest.

❌ Objection 3 : Further, as the merits of priests differ in the point of being good and better, so they likewise differ in the point of being good and bad. Consequently, if the mass of a better priest be itself better, it follows that the mass of a bad priest must be bad. Now this is unreasonable, because the malice of the ministers cannot affect Christ's mysteries, as Augustine says in his work on Baptism (Contra Donat. xii). Therefore neither is the mass of a better priest the better.
