In the Likeness of Melchizedek
A.W. Pink: God designed that the Lord Jesus should in all things have the pre-eminence. This was due Him because of the glory of His person and the transcendent excellency of His work. Christ is the center of all God’s counsels, the key to every problem. All things are being directed to His ultimate honor and praise. The Levitical priesthood, with its mysteries and shadows, served as a suitable background, from which might shine forth the more gloriously the full blaze of God’s perfections made manifest by His incarnate Son.
Now if perfection had been attainable through the Levitical priesthood (for under it the people received the law), what further need would there have been for another priest to arise after the order of Melchizedek, rather than one named after the order of Aaron? For when there is a change in the priesthood, there is necessarily a change in the law as well. For the one of whom these things are spoken belonged to another tribe, from which no one has ever served at the altar. For it is evident that our Lord was descended from Judah, and in connection with that tribe Moses said nothing about priests.
This becomes even more evident when another priest arises in the likeness of Melchizedek, who has become a priest, not on the basis of a legal requirement concerning bodily descent, but by the power of an indestructible life. For it is witnessed of him,
“You are a priest forever,
after the order of Melchizedek.”
For on the one hand, a former commandment is set aside because of its weakness and uselessness (for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God.
