Martin Chemnitz on the Two Natures in Christ, Part 1
“The Fathers also teach that He wills to demonstrate His human nature when He deals with us and works in us in His activities as Savior, so that He thereby might bestow His grace and benefits upon us. For the power, grace, efficacy, merits, and blessings of Christ are not communicated to believers outside of or without His person, as if He Himself were not present, as the adversaries themselves admit. They also admit that it is necessary above all things that Christ Himself be given to us, that He become ours, and that He be present with us and joined to us, so that from Him and in Him and through Him we might be filled with all the fullness of God (Eph. 3:19).”
