"Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them." (Hebrews 7:25)
Melchizedek, king of Salem and priest of God Most High, met Abraham returning from the defeat of the kings and blessed him. Abraham gave him a tenth of everything. His name means king of righteousness; king of Salem means king of peace. He is without father or mother, without genealogy, without beginning of days or end of life, resembling the Son of God, he remains a priest forever. The author's point is precise: the Levitical priesthood, which derives its authority from descent from Aaron, is a temporary institution. Melchizedek's priesthood precedes and transcends the Levitical order. When Psalm 110 declares that the Messiah is a priest forever in the order of Melchizedek, it announces a priesthood that supersedes the Law of Moses.
If perfection could have been attained through the Levitical priesthood, why was there still need for another priest to come, one in the order of Melchizedek? When there is a change of the priesthood, there must also be a change of the law. The former regulation is set aside because it was weak and useless, for the Law made nothing perfect. A better hope is introduced by which we draw near to God. Jesus has become the guarantor of a better covenant.
The Levitical priests were prevented by death from continuing in office. But because Jesus lives forever, he has a permanent priesthood. Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them. Such a high priest truly meets our need: holy, blameless, pure, set apart from sinners, exalted above the heavens. He sacrificed for their sins once for all when he offered himself. The Catechism calls the eternal intercession of Christ the permanent foundation of all Christian prayer: at this very moment, Christ is presenting the merits of his sacrifice before the Father on your behalf (CCC 1544).
Brothers and sisters, he always lives to intercede for you. Not once. Not occasionally. Always. At this moment, the eternal priest is presenting your name and your need before the Father. The intercession never stops. You are never outside the reach of the prayer of the one who lives forever. Pray with the confidence of one who is being prayed for constantly by the priest who never sleeps.
Lord Jesus, priest forever in the order of Melchizedek, you always live to intercede for us. Save us completely, for we come to God through you alone. Holy, blameless, pure, you offered yourself once for all. Let your eternal intercession be our confidence before the Father. Through Christ our Lord. Amen.
