Hebrews 1:1-3

The aim of the writer is to prove that the old Covenant through which God had dealt with the Hebrews is superseded by the New; and this aim he accomplishes in the first place by exhibiting the superiority of the mediator of the new Covenant to all previous mediators. The Epistle holds in literature the place which the Transfiguration holds in the life of Christ. Former mediators give place and Christ is left alone under the voice “Hear ye Him”. With this writer, Jesus is before all else the Mediator of a better Covenant, Hebrews 8:6. But ‘Mediator' involves the arranging and accomplishing of everything required for the efficacy of the Covenant; the perfect knowledge of the person and purposes of Him who makes the Covenant with men and the communication of this knowledge to them; together with the removal of all obstacles to man's entrance into the fellowship with God implied by the Covenant. This twofold function is in these first three verses shown to be discharged by Christ. He as Son speaks to men for God and thus supersedes all previous revelations; while, instead of appointing a priest who can only picture a cleansing, and accomplish a ceremonial purity, He becomes Priest and actually cleanses men from sin, and so effects their actual fellowship with God.
