Got Solid Food? King of Righteousness, King of Peace, Priest of the Most High God
Those with appetite for “solid food” are brought to understanding via in-depth study beginning with the last half of Hebrews 6 that “hope [is] like a sure and firm anchor of the soul” [v. 19 (HCSB)] if it rests in the “high priest forever in the order of Melchizedek” (v. 20) — Jesus — and that hope is illusory if it rests in other than Him, the Priest-King. As Dr. John MacArthur advocated via Hard To Believe: The High Cost and Infinite Value of Following Jesus, the wide gate and broad road that leads to destruction (Matthew 7:13) is prevalently marked “Jesus”; alas, it’s not Jesus the Priest-King which interests the unregenerate. Astonishingly, even among the regenerate elect, Truth regarding the Priest-King is quenched; evisceration of the church via concomitant woeful beliefs and practices has been and continues to be the result.
At Hebrews 5:6, remember, the Writer quoted Psalm 110:4: “You are a priest forever in the order of Melchizedek”. At 5:12, the Writer lamented: “You need milk, not solid food”. At 6:4 – 8, the Writer solemnly warns those satisfied with “milk” of their inevitable curse and burning; faith without appetite is dead (assuming mental capacity).
[Then], the author [] related his readers’ condition to the purpose of God, as evidenced especially in his dealings with Abraham. In [6:20], the author completes his careful preparaton for the ‘teaching difficult to explain’ (5:11). He does this by a skilful combination of motifs: (1) traditional teaching about the resurrection or exaltation of Christ is re-expressed in terms of the entry of a high priest into the inner sanctuary; and (2) the contrast between Jesus’ ministry and that of the OT priesthood is expressed by use of the Melchizedek motif. This comparison and contrast, both based on exegesis of OT texts, will prove to be the heart of the epistle.
Paul Ellingworth, The New International Greek Testament Commentary ~ The Epistle to the Hebrews, pp. 347 – 348 (link previously provided). The “heart of the epistle” is, indeed, the expostion of its central theme: The New Covenant. The Writer
argues powerfully that a new priesthood signals a new covenant. You cannot graft Christ’s high-priesthood onto that of the Mosaic order. Nor can the Mosaic priesthood survive under the ‘better covenant’ established in Christ’s atoning blood. There is a new covenant and a new priesthood, and former things have passed away.
