Whether the priesthood of Christ endures for ever?

❌ Objection 1 : It would seem that the priesthood of Christ does not endure for ever. For as stated above (Article [4], ad 1,3) those alone need the effect of the priesthood who have the weakness of sin, which can be expiated by the priest's sacrifice. But this will not be for ever. For in the Saints there will be no weakness, according to Is. 60:21: "Thy people shall be all just": while no expiation will be possible for the weakness of sin, since "there is no redemption in hell" (Office of the Dead, Resp. vii). Therefore the priesthood of Christ endures not for ever.

❌ Objection 2 : Further, the priesthood of Christ was made manifest most of all in His passion and death, when "by His own blood He entered into the Holies" (Heb. 9:12). But the passion and death of Christ will not endure for ever, as stated Rm. 6:9: "Christ rising again from the dead, dieth now no more." Therefore the priesthood of Christ will not endure for ever.

❌ Objection 3 : Further, Christ is a priest, not as God, but as man. But at one time Christ was not man, namely during the three days He lay dead. Therefore the priesthood of Christ endures not for ever.
