And after the immortality and incorruptibility of His body He called Himself Son of Man, naming Himself from the nature which was seen, inasmuch as the divine nature is indeed invisible to angels, as the Lord Himself had said “No one has seen God at any time.” And to the great Moses He said “There shall no man see me and live.”
The words “Henceforth know we no man after the flesh; yea, though we have known Christ after the flesh; yet now henceforth know we Him no more,” were not written by the divine Apostle in order to annul the assumed nature, but for the confirmation of our own future incorruption, immortality, and spiritual life.
The Apostle therefore continues “Therefore if any man be in Christ he is a new creature; old things are passed away; behold all things have become new.” He speaks of what is to be in the future as though it had already come to pass. We have not yet been gifted with immortality, but we shall be; and when so gifted we shall not become bodiless, but we shall put on immortality. “For” says the divine Apostle, “we would not be unclothed, but clothed upon, that mortality might be swallowed up of life.” And again “For this corruptible must put on incorruption, and this mortal must put on immortality.” Thus he did not speak of the Lord as bodiless, but taught us to believe that even the visible nature is incorruptible, and glorified with the divine glory. This instruction he has given us yet more clearly in the Epistle to the Philippians; “For our conversation” he writes “is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ; who shall change our vile body, that it may be fashioned like his glorious body.” By these words he teaches us distinctly that the body of the Lord is a body, but a divine body, and glorified with the divine glory.
Let us, then, not shun the name whereby we enjoy salvation, and whereby all things are made new, as says our teacher himself in his Epistle to the Ephesians,— “According to His good pleasure which He has purposed in Himself; that in the dispensation of the fullness of time He might gather together in one all things in Christ, both which are in heaven, and which are on earth, even in Him.” Let us rather learn from this blessed language how we are bound to glorify our benefactor, by connecting the name of Christ with our God and Father. In his Epistle to the Romans the Apostle says “my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, but now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith; to God only will be glory through Jesus Christ forever. Amen.” Writing to the Ephesians he thus gives praise— “Now unto Him that is able to do exceeding abundantly above all that we ask or think, according to the power that works in us, unto Him be glory in the Church by Christ Jesus throughout all ages, world without end. Amen.” And a little before he says, “For this cause I bow my knee unto the Father of our Lord Jesus Christ of whom the whole family in heaven and earth is named.” And considerably farther on he says “Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ.” And when he requites with benediction the liberality of the Philippians he says “But my God shall supply all your need according to His riches in glory by Christ Jesus.” And for the Hebrews he prayed, “Now the God of peace, that brought again from the dead our Lord Jesus Christ, that great shepherd of the sheep, through the blood of the everlasting covenant, make you perfect in every good work, to do His will, working in you that which is well pleasing in His sight, through Jesus Christ; to whom be glory for ever and ever. Amen.” And not only when glorifying, but also when exhorting and protesting, the Apostle conjoins the Christ with God the Father. To the blessed Timothy he exclaims “I charge you therefore before God and the Lord Jesus Christ.” And again “I give you charge in the sight of God who quickens all things, and before Jesus Christ, who before Pontius Pilate witnessed a good confession; that thou keep this commandment without spot, unrebukable, until the appearing of our Lord Jesus Christ; which in His times He shall show, who is the blessed and only Potentate, the King of kings and Lord of lords; who only has immortality, dwelling in the light which no man can approach unto; whom no man has seen, nor can see; to whom be honour and power everlasting. Amen.”
These are the lessons we have learned from the divine Apostles; this is the teaching given us by John and Matthew, those mighty rivers of the gospel message. The latter says “The book of the generation of Jesus Christ the son of David, the son of Abraham;” and the former when he showed the things which were before the ages wrote, “In the beginning was the Word and the Word was with God and the Word was God. The same was in the beginning with God. All things were made by Him.”
