"And beginning from Moses and from all the prophets, He interpreted to them in all the Scriptures the things concerning Himself." It will be observed that our Evangelist uses a peculiar word in speaking of this Divine exposition. He calls it an "interpretation," a word used in the New Testament only in the sense of translating from one language to another, from the unknown to the known tongue. And such, indeed, it was; for they had read the Scriptures but in part, and so misread them. They had thrown upon those Scriptures the projections of their own hopes and illusions; while other Scriptures, those relating to the sufferings of Christ, were set back, out of sight, or if heard at all, they were only the voice of an unknown tongue, a _vox et preterea nihil_. So Jesus interprets to them the voices of this unknown tongue. Beginning at Moses, He shows, from the types, the prophecies, and the Psalms, how that the Christ must suffer and die, ere the glories of His kingdom can begin; that the cross and the grave both lay in the path of the Redeemer, as the bitter and prickly calyx out of which the "glories" should unfold themselves. And thus, opening their Scriptures, putting in the crimson lens of the blood, as well as the chromatic lens of the Messianic glory, the disciples find the cross all transfigured, inwoven in God's eternal purpose of redemption; while the sufferings of Christ, at which they had stumbled before, they now see were part of the eternal plan of mercy, a Divine "ought," a great necessity.
