In this reading from the Letter to the Hebrews, St. Paul reminds us that Christ is the great high priest, like us in all things but sin. He was tempted, so he can understand our temptation; but being perfect, He was able to offer Himself as the perfect Sacrifice to God the Father. That sacrifice is the source of the eternal salvation of all who believe in Christ.
Having therefore a great high priest that hath passed into the heavens, Jesus the Son of God: let us hold fast our confession. For we have not a high priest, who can not have compassion on our infirmities: but one tempted in all things like as we are, without sin. Let us go therefore with confidence to the throne of grace: that we may obtain mercy, and find grace in seasonable aid.
For every high priest taken from among men, is ordained for men in the things that appertain to God, that he may offer up gifts and sacrifices for sins: Who can have compassion on them that are ignorant and that err: because he himself also is compassed with infirmity. And therefore he ought, as for the people, so also for himself, to offer for sins. Neither doth any man take the honour to himself, but he that is called by God, as Aaron was.
So Christ also did not glorify himself, that he might be made a high priest: but he that said unto him: Thou art my Son, this day have I begotten thee. As he saith also in another place: Thou art a priest for ever, according to the order of Melchisedech.
Who in the days of his flesh, with a strong cry and tears, offering up prayers and supplications to him that was able to save him from death, was heard for his reverence. And whereas indeed he was the Son of God, he learned obedience by the things which he suffered: And being consummated, he became, to all that obey him, the cause of eternal salvation. Called by God a high priest according to the order of Melchisedech.
