Whether a degraded priest can consecrate this sacrament?

❌ Objection 1 : It seems that a degraded priest cannot consecrate this sacrament. For no one can perform this sacrament except he have the power of consecrating. But the priest "who has been degraded has no power of consecrating, although he has the power of baptizing" (App. Gratiani). Therefore it seems that a degraded priest cannot consecrate the Eucharist.

❌ Objection 2 : Further, he who gives can take away. But the bishop in ordaining gives to the priest the power of consecrating. Therefore he can take it away by degrading him.

❌ Objection 3 : Further, the priest, by degradation, loses either the power of consecrating, or the use of such power. But he does not lose merely the use, for thus the degraded one would lose no more than one excommunicated, who also lacks the use. Therefore it seems that he loses the power to consecrate, and in consequence that he cannot perform this sacrament.
