Book XI. The Faith is one, even as God is One; but the faiths of heretics are many (§§ 1, 2). Hilary has now demonstrated the truth about Christ, so that it cannot be denied; it is attested also by miracles even in his own day (§ 3). The Arians preach another, a created Christ; and in making Christ a creature they proclaim another God, not a Father but a Creator (§ 4). The Son, as the Image, is of one nature with the Father; if He is inferior He is not the Image (§ 5). But the Arians explain the oneness away by arguments from His condescension to our estate (§ 6), and, even after His Resurrection, plead that He confesses His inequality. They argue thus from 1 Cor. xv. 24-28, a passage to which the rest of this book is devoted (§§ 7, 8). But we must recognise the mysteriousness of the truth, accepting the two sides of it, both clearly revealed though we cannot reconcile them (§ 9). They regard only one aspect; Hilary in reply proves once more that Christ is both born from God, and Himself God (§§ 10-12). But at His Incarnation He began to have as Lord the God Who had been His Father eternally (§ 13), and when He said that He was ascending to His God, He spoke as when He calls us His brethren (§§ 14, 15). Thus there are two senses in which God is the Father of Christ; and He Who is Father to Christ the Son is Lord to Christ the Servant (§§ 16, 17). And it was to Him as Servant that the Psalmist said, Your God has anointed You, the words would have no meaning if addressed to Him as Son (§§ 18, 19). It is through this lower nature that He is our Brother and God our Father, and He the Mediator (§ 20). But it is argued that His subjection at the last and the delivery of the kingdom to the Father is a proof of inequality. The passage must be taken as a whole (§§ 21, 22). There are some truths which it is difficult for man to grasp, and if we misunderstand them we must not be ashamed to confess our error (§§ 23, 24). In this passage the Arians aid their case by changing the order of the prophecy (§§ 25-27). The end means a final and enduring state, not the coming to an end (§ 28), and though He delivers up the kingdom He does not cease to reign (§ 29). His subjection to the Father and the subjection of all things to Him is next considered; in one sense it is figurative language, in another it proves the unity of Father and Son. The subjection of the Son means His partaking in the glory of the Father (§§ 30-36). The Transfiguration shows the glory of Christ’s Body; a glory which the faithful shall share (§§ 37, 38). The righteous are His kingdom, which He, as Man, shall deliver to the Father, for By man came also the resurrection of the dead (§ 39). And at last God shall be all in all, humanity in Christ not being discarded, but glorified and received into the Godhead (§ 40). Christ, as well as St. Paul, has foretold this (§§ 41, 42). The Arian misrepresentation of this truth is mere folly (§ 43). Any rational explanation must assume that God’s majesty cannot be augmented, even as it cannot be measured (§§ 44, 45), while our reason is limited, and so contrasted with the Divine infinity. God cannot become greater than He was in becoming All in all. Father and Son, after as before, must Each be as He was (§§ 46-48). All was done for us that we might be glorified, being conformed to the likeness of Him Who is the Image of the Father (§ 49).

  1. The Apostle in his letter to the Ephesians, reviewing in its manifold aspects the full and perfect mystery of the Gospel, mingles with other instructions in the knowledge of God the following: As ye also were called in one hope of your calling; One Lord, one faith, one baptism, one God and Father of all, and through all, and in us all. He does not leave us in the vague and misleading paths of an indefinite teaching, or abandon us to the shifting fancies of imagination, but limits the unimpeded license of intellect and desire by the appointment of restraining barriers. He gives us no opportunity to be wise beyond what he preached, but defines in exact and precise language the faith fixed for all time, that there may be no excuse for instability of belief. He declares one faith, as he preaches one Lord, and pronounces one baptism, as he declares one faith of one Lord, that as there is one faith of one Lord, so there may be one baptism of one faith in one Lord. And since the whole mystery of the baptism and the faith is not only in one Lord, but also in one God, he completes the consummation of our hope by the confession of one God. The one baptism and the one faith are of one God, as they are of one Lord. Lord and God are each one, not by union of person but by distinction of properties: for, on the one hand, it is the property of Each to be one, whether of the Father in His Fatherhood, or of the Son in His Sonship, and on the other hand, that property of individuality, which Each possesses, constitutes for Each the mystery of His union with the Other. Thus the one Lord Christ cannot take away from God the Father His Lordship, or the one God the Father deny to the one Lord Christ His Godhead. If, because God is one, Christ is not also by nature divine, then we cannot allow that the one God is Lord, because there is one Lord Christ: that is, on the supposition that by their oneness’ is signified not the mystery, but an exclusive unity. So there is one baptism and one faith of one Lord, as of one God.

  2. But how can it be any longer one faith, if it does not steadfastly and sincerely confess one Lord and one God the Father: and how can the faith which is not one faith confess one Lord and one God the Father? Further, how can the faith be one, when its preachers are so at variance? One comes teaching that the Lord Jesus Christ, being in the weakness of our nature, groaned with anguish when the nails pierced His hands, that He lost the virtue of His own power and nature, and shrank shuddering from the death which threatened Him. Another even denies the cardinal doctrine of the Generation and pronounces Him a creature. Another will call Him, but not think Him, God on the ground that religion allows us to speak of more Gods than One, but He, Whom we recognise as God, must be conscious of sharing the divine nature. Again, how can Christ the Lord be one, when some say that as God He feels no pain, others make Him weak and fearful: to some He is God in name, to others God in nature: to some the Son by Generation, to others the Son by appellation? And if this is so, how can God the Father be one in the faith, when to some He is Father by His authority, to others Father by generation, in the sense that God is Father of the universe?
