11 If perfection could have been attained through the Levitical priesthood-and indeed the law given to the people established that priesthood-why was there still need for another priest to come, one in the order of Melchizedek, not in the order of Aaron? 12 For when the priesthood is changed, the law must be changed also. 13 He of whom these things are said belonged to a different tribe, and no one from that tribe has ever served at the altar. 14 For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. 15 And what we have said is even more clear if another priest like Melchizedek appears, 16 one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life. 17 For it is declared: "You are a priest forever, in the order of Melchizedek."[1] 18 The former regulation is set aside because it was weak and useless 19 (for the law made nothing perfect), and a better hope is introduced, by which we draw near to God. 20 And it was not without an oath! Others became priests without any oath, 21 but he became a priest with an oath when God said to him: "The Lord has sworn and will not change his mind: 'You are a priest forever.' "[2] 22 Because of this oath, Jesus has become the guarantor of a better covenant. 23 Now there have been many of those priests, since death prevented them from continuing in office; 24 but because Jesus lives forever, he has a permanent priesthood. 25 Therefore he is able to save completely[3] those who come to God through him, because he always lives to intercede for them.

Commentary on Hebrews 7:11-25

(Read Hebrews 7:11-25)

The priesthood and law by which perfection could not come, are done away; a Priest is risen, and a dispensation now set up, by which true believers may be made perfect. That there is such a change is plain. The law which made the Levitical priesthood, showed that the priests were frail, dying creatures, not able to save their own lives, much less could they save the souls of those who came to them. But the High Priest of our profession holds his office by the power of endless life in himself; not only to keep himself alive, but to give spiritual and eternal life to all who rely upon his sacrifice and intercession. The better covenant, of which Jesus was the Surety, is not here contrasted with the covenant of works, by which every transgressor is shut up under the curse. It is distinguished from the Sinai covenant with Israel, and the legal dispensation under which the church so long remained. The better covenant brought the church and every believer into clearer light, more perfect liberty, and more abundant privileges. In the order of Aaron there was a multitude of priests, of high priests one after another; but in the priesthood of Christ there is only one and the same. This is the believer's safety and happiness, that this everlasting High Priest is able to save to the uttermost, in all times, in all cases. Surely then it becomes us to desire a spirituality and holiness, as much beyond those of the Old Testament believers, as our advantages exceed theirs.
