In how many ways “Through whom” is used; and in what sense “with whom” is more suitable. Explanation of how the Son receives a commandment, and how He is sent.
17. When, then, the apostle “thanks God through Jesus Christ,” and again says that “through Him” we have “received grace and apostleship for obedience to the faith among all nations,” or “through Him have access unto this grace wherein we stand and rejoice,” he sets forth the boons conferred on us by the Son, at one time making the grace of the good gifts pass through from the Father to us, and at another bringing us to the Father through Himself. For by saying “through whom we have received grace and apostleship,” he declares the supply of the good gifts to proceed from that source; and again in saying “through whom we have had access,” he sets forth our acceptance and being made “of the household of God” through Christ. Is then the confession of the grace wrought by Him to usward a detraction from His glory? Is it not truer to say that the recital of His benefits is a proper argument for glorifying Him? It is on this account that we have not found Scripture describing the Lord to us by one name, nor even by such terms alone as are indicative of His godhead and majesty. At one time it uses terms descriptive of His nature, for it recognises the “name which is above every name,” the name of Son, and speaks of true Son, and only begotten God, and Power of God, and Wisdom, and Word. Then again, on account of the various manners wherein grace is given to us, which, because of the riches of His goodness, according to his manifold wisdom, he bestows on them that need, Scripture designates Him by innumerable other titles, calling Him Shepherd, King, Physician, Bridegroom, Way, Door, Fountain, Bread, Axe, and Rock. And these titles do not set forth His nature, but, as I have remarked, the variety of the effectual working which, out of His tender-heartedness to His own creation, according to the peculiar necessity of each, He bestows upon them that need. Them that have fled for refuge to His ruling care, and through patient endurance have mended their wayward ways, He calls “sheep,” and confesses Himself to be, to them that hear His voice and refuse to give heed to strange teaching, a “shepherd.” For “my sheep,” He says, “hear my voice.” To them that have now reached a higher stage and stand in need of righteous royalty, He is a King. And in that, through the straight way of His commandments, He leads men to good actions, and again because He safely shuts in all who through faith in Him betake themselves for shelter to the blessing of the higher wisdom, He is a Door.
So He says, “By me if any man enter in, he shall go in and out and shall find pastare.” Again, because to the faithful He is a defence strong, unshaken, and harder to break than any bulwark, He is a Rock. Among these titles, it is when He is styled Door, or Way, that the phrase “through Him” is very appropriate and plain. As, however, God and Son, He is glorified with and together with the Father, in that “at, the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.” Wherefore we use both terms, expressing by the one His own proper dignity, and by the other His grace to usward.
18. For “through Him” comes every succour to our souls, and it is in accordance with each kind of care that an appropriate title has been devised. So when He presents to Himself the blameless soul, not having spot or wrinkle, like a pure maiden, He is called Bridegroom, but whenever He receives one in sore plight from the devil's evil strokes, healing it in the heavy infirmity of its sins, He is named Physician. And shall this His care for us degrade to meanness our thoughts of Him? Or, on the contrary, shall it smite us with amazement at once at the mighty power and love to man of the Saviour, in that He both endured to suffer with us in our infirmities, and was able to come down to our weakness? For not heaven and earth and the great seas, not the creatures that live in the water and on dry land, not plants, and stars, and air, and seasons, not the vast variety in the order of the universe, so well sets forth the excellency of His might as that God, being incomprehensible, should have been able, impassibly, through flesh, to have come into close conflict with death, to the end that by His own suffering He might give us the boon of freedom from suffering. The apostle, it is true, says, “In all these things we are more than conquerors through him that loved us.” But in a phrase of this kind there is no suggestion of any lowly and subordinate ministry, but rather of the succour rendered “in the power of his might.” For He Himself has bound the strong man and spoiled his goods, that is, us men, whom our enemy had abused in every evil activity, and made “vessels meet for the Master's use” us who have been perfected for every work through the making ready of that part of us which is in our own control. Thus we have had our approach to the Father through Him, being translated from “the power of darkness to be partakers of the inheritance of the saints in light.” We must not, however, regard the œconomy through the Son as a compulsory and subordinate ministration resulting from the low estate of a slave, but rather the voluntary solicitude working effectually for His own creation in goodness and in pity, according to the will of God the Father. For we shall be consistent with true religion if in all that was and is from time to time perfected by Him, we both bear witness to the perfection of His power, and in no case put it asunder from the Father's will. For instance, whenever the Lord is called the Way, we are carried on to a higher meaning, and not to that which is derived from the vulgar sense of the word. We understand by Way that advance to perfection which is made stage by stage, and in regular order, through the works of righteousness and “the illumination of knowledge;” ever longing after what is before, and reaching forth unto those things which remain, until we shall have reached the blessed end, the knowledge of God, which the Lord through Himself bestows on them that have trusted in Him. For our Lord is an essentially good Way, where erring and straying are unknown, to that which is essentially good, to the Father. For “no one,” He says, comes to the Father but [“by” A.V.] through me. Such is our way up to God “through the Son.”
