Hebrews 8:3

πᾶς γὰρ ἀρχιερεὺς.… “For every High Priest is appointed for the offering of gifts and sacrifices, and therefore it was necessary that this man also have something to offer”. That Christ is in heaven as a λειτουργός, as an active minister in holy things, is proved by the universal law, that every High Priest is appointed to offer gifts and sacrifices. Christ is not idle in heaven, but being there as High Priest He must be offering something; what that is, He has told us in Hebrews 7:27, but here no emphasis is on the what, but merely on the fact that He must be offering something, must be actively ministering in heaven as a λειτουργός. [Bruce therefore overlooks Hebrews 7:27 in his interpretation: “He is content for the present to throw out the remark: ‘This man must have something to offer,' and to leave his readers for a while to puzzle over the question, What is it?”] With ἀναγκαῖον some have understood ἦν rather than ἐστὶ “necesse fuit habere quod offerret” (Beza) followed by Westcott, etc., on the ground that the reference is to our Lord's presentation to the Father of His finished sacrifice. But it is better to give the word a merely logical and subjective force; it is a necessary inference that this man, etc. Behind and beyond this lies no doubt the reference to Christ's sacrifice. As the High Priest could not enter into the Holiest without the blood of the victim (Hebrews 9:7), so must Jesus accomplish His priestly office by offering His own blood (Hebrews 9:12). For the words of the former part of the verse see note on Hebrews 6:1.
