EIGHTH ARTICLE [III, Q. 82, Art. 8]

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.

Obj. 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.

Obj. 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.

_On the contrary,_ Augustine (Contra Parmen. ii) proves that

"apostates" from the faith "are not deprived of their Baptism," from

the fact that "it is not restored to them when they return repentant;

and therefore it is deemed that it cannot be lost." But in like

fashion, if the degraded man be restored, he has not to be ordained

over again. Consequently, he has not lost the power of consecrating,

and so the degraded priest can perform this sacrament.

_I answer that,_ The power of consecrating the Eucharist belongs to

the character of the priestly order. But every character is

indelible, because it is given with a kind of consecration, as was

said above (Q. 63, A. 5), just as the consecrations of all other

things are perpetual, and cannot be lost or repeated. Hence it is

clear that the power of consecrating is not lost by degradation. For,

again, Augustine says (Contra Parmen. ii): "Both are sacraments,"

namely Baptism and order, "and both are given to a man with a kind of

consecration; the former, when he is baptized; the latter when he is

ordained; and therefore it is not lawful for Catholics to repeat

either of them." And thus it is evident that the degraded priest can

perform this sacrament.

Reply Obj. 1: That Canon is speaking, not as by way of assertion, but

by way of inquiry, as can be gleaned from the context.

Reply Obj. 2: The bishop gives the priestly power of order, not as

though coming from himself, but instrumentally, as God's minister,

and its effect cannot be taken away by man, according to Matt. 19:6:

"What God hath joined together, let no man put asunder." And

therefore the bishop cannot take this power away, just as neither can

he who baptizes take away the baptismal character.

Reply Obj. 3: Excommunication is medicinal. And therefore the

ministry of the priestly power is not taken away from the

excommunicate, as it were, perpetually, but only for a time, that

they may mend; but the exercise is withdrawn from the degraded, as

though condemned perpetually.
