A heresy which arose in the fourth century, and denied the Divinity of {ln:Jesus} Christ.

DOCTRINE

First among the doctrinal disputes which troubled Christians after Constantine had recognized the Church in A.D. 313, and the parent of many more during some three centuries, Arianism occupies a large place in ecclesiastical history. It is not a modern form of unbelief, and therefore will appear strange in modern eyes. But we shall better grasp its meaning if we term it an Eastern attempt to rationalize the creed by stripping it of mystery so far as the relation of Christ to God was concerned. In the New Testament and in Church teaching {ln:Jesus} of Nazareth appears as the Son of God. This name He took to Himself (Matthew 11:27; John 10:36), while the Fourth Gospel declares Him to be the Word (Logos), Who in the beginning was with God and was God, by Whom all things were made. A similar doctrine is laid down by St. Paul, in his undoubtedly genuine Epistles to the Ephesians, Colossians, and Philippians. It is reiterated in the Letters of Ignatius, and accounts for Pliny's observation that Christians in their assemblies chanted a hymn to Christ as God. But the question how the Son was related to the Father (Himself acknowledged on all hands to be the one Supreme Deity), gave rise, between the years A.D. 60 and 200, to a number of Theosophic systems, called generally Gnosticism, and having for their authors Basilides, Valentinus, Tatian, and other Greek speculators. Though all of these visited Rome, they had no following in the West, which remained free from controversies of an abstract nature, and was faithful to the creed of its baptism. Intellectual centres were chiefly Alexandria and Antioch, Egyptian or Syrian, and speculation was carried on in Greek. The Roman Church held steadfastly by tradition. Under these circumstances, when Gnostic schools had passed away with their "conjugations" of Divine powers, and "emanations" from the Supreme unknowable God (the "Deep" and the "Silence") all speculation was thrown into the form of an inquiry touching the "likeness" of the Son to His Father and "sameness" of His Essence. Catholics had always maintained that Christ was truly the Son, and truly God. They worshipped Him with divine honours; they would never consent to separate Him, in idea or reality, from the Father, Whose Word, Reason, Mind, He was, and in Whose Heart He abode from eternity. But the technical terms of doctrine were not fully defined; and even in Greek words like essence (ousia), substance (hypostasis), nature (physis), person (hyposopon) bore a variety of meanings drawn from the pre-Christian sects of philosophers, which could not but entail misunderstandings until they were cleared up. The adaptation of a vocabulary employed by Plato and Aristotle to Christian truth was a matter of time; it could not be done in a day; and when accomplished for the Greek it had to be undertaken for the Latin, which did not lend itself readily to necessary yet subtle distinctions. That disputes should spring up even among the orthodox who all held one faith, was inevitable. And of these wranglings the rationalist would take advantage in order to substitute for the ancient creed his own inventions. The drift of all he advanced was this: to deny that in any true sense God could have a Son; as Mohammed tersely said afterwards, "God neither begets, nor is He begotten" (Koran, 112). We have learned to call that denial Unitarianism. It was the ultimate scope of Arian opposition to what Christians had always believed. But the Arian, though he did not come straight down from the Gnostic, pursued a line of argument and taught a view which the speculations of the Gnostic had made familiar. He described the Son as a second, or inferior God, standing midway between the First Cause and creatures; as Himself made out of nothing, yet as making all things else; as existing before the worlds of the ages; and as arrayed in all divine perfections except the one which was their stay and foundation. God alone was without beginning, unoriginate; the Son was originated, and once had not existed. For all that has origin must begin to be.

Such is the genuine doctrine of Arius. Using Greek terms, it denies that the Son is of one essence, nature, or substance with God; He is not consubstantial () with the Father, and therefore not like Him, or equal in dignity, or co-eternal, or within the real sphere of Deity. The Logos which St. John exalts is an attribute, Reason, belonging to the Divine nature, not a person distinct from another, and therefore is a Son merely in figure of speech. These consequences follow upon the principle which Arius maintains in his letter to Eusebius of Nicomedia, that the Son "is no part of the Ingenerate." Hence the Arian sectaries who reasoned logically were styled Anomoeans: they said that the Son was "unlike" the Father. And they defined God as simply the Unoriginate. They are also termed the Exucontians (ex ouk onton), because they held the creation of the Son to be out of nothing. +
