""For if through the offence of one many be dead; much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many." It was to set forth a perfect pattern of renewed humanity that Our Lord became incarnate, "for with power He created the world, but restored it by obedience." By this means was perfected that example of human nature, which from the time of its conception was without weakness or defilement. But this perfection it had, not like Adam from the mere absence of guilt, but from the presence of that Deity with which it was personally one. That exhaustless grace, which was to be the principle of life to the whole renewed family, had its fountain and well-head in the manhood of the Son of God, before it was portioned out to the innumerable generations of His spiritual progeny. And thus "being made perfect, He became the author of eternal salvation unto all them that obey Him." To this end was His man's nature so sorely exercised, that it might be the seed of life to all His members. So much He Himself tells us respecting His human nature, declaring that He purified it, that it might be a fit source of grace for all men: "For their sakes I sanctify Myself, that they also might be sanctified through the truth." And this sanctifying truth is no other than that Divine Being, who applies the virtue of His own manhood to His servants: "Sanctify them through Thy truth, Thy Word is truth." So that by union with His humanity does He bestow upon all the members in their degree, that which pertains perfectly to the Head of the body by nature. As St. Athanasius expresses it, the Eternal "Word was not weakened by taking a body, as though for Himself He needed to receive grace, but rather He deified that which He put on -- nay, He graciously bestowed it upon the family of men."(Con. Arian. i. 42.) Thus did His humanity become "the leaven of the whole lump," that through itself it might "sanctify the whole race of man."(S. Gregor. Naz. Hom. xxxvi. 89.) It was the city set on a hill, (St. Hilary, on Matt. iv. 12.) in which all the kindred of the renewed are inhabitants. For this reason is "the fellowship of the Holy Ghost" the very consummation of the Church's blessing, as implying that through His power all renewed men have communion with the body of Christ and with one another."
