Trinitarian scholar, minister, and missionary, H. R. Boer admits: The very first Christians to really discuss Jesus’ relationship to God in their writings were the Apologists.
“Justin and the other Apologists therefore taught that the Son is a creature. He is a high creature, a creature powerful enough to create the world, but nevertheless, a creature. In theology this relationship of the Son to the Father is called Subordinationism. The Son is subordinate, that is, secondary to, dependent upon, and caused by the Father.” - p. 110, A Short History of the Early Church, Eerdmans (trinitarian), 1976.
Other respected scholars agree.
“Before the Council of Nicaea (AD 325) all theologians viewed the Son as in one way or another subordinate to the Father.” - pp. 112-113, Eerdman’s Handbook to the History of Christianity (trinitarian), 1977; and p. 114, The History of Christianity, A Lion Handbook, Lion Publishing, 1990 revised ed.
“The formulation ‘One God in three persons’ was not solidly established, certainly not fully assimilated into Christian life and its profession of faith prior to the end of the 4th century. But it is precisely this formulation that has first claim to the title the Trinitarian Dogma. Among the Apostolic Fathers [those very first Christians who had known and been taught by the Apostles and their disciples], there had been nothing even remotely approaching such a mentality or perspective.” - New Catholic Encyclopedia, p. 299, v. 14, 1967.
Justin Martyr (c. 100-165 A.D.)
Justin, whom the trinitarian The Oxford Dictionary of the Christian Church (p. 770) called “the most outstanding of the ‘Apologists,’” wrote:
God alone is unbegotten and incorruptible, and therefore He is God, but all other things after him are created and corruptible {Justin has just concurred that the world was begotten by God} .... take your stand on one Unbegotten, and say this is the Cause of all. - The Ante-Nicene Fathers (ANF) 1:197 (‘Dialogue’).
Nevertheless, in Justin’s picture, as later in Tertullian’s, the generation of the Logos takes place only with a view to the world’s creation. The Son, therefore, is not co-eternal with God; Moreover, he exists to provide a mediator between God and the cosmos in creation and revelation, as the language of John 1:3 and 1:18, not to mention 1 Corinthians 8:6, seemed to suggest. Thus, the Logos theology appeared to introduce a ‘second God’ {deuteros theos - ‘a second god’ was the well-known term used by Philo and many of the second century Christian writers - see the LOGOS study} inconsistently with the principle of monotheism; and further, it suggested that the Logos represented a secondary grade or kind of divinity. It ‘subordinated’ the Son to the Father. - p. 84, A History of the Christian Church, Walker (trinitarian), Scribner’s, 1985 printing.
Irenaeus (c. 140-203 A.D.)
“... neither the prophets, nor the apostles, nor the Lord Christ in His own person, did acknowledge any other Lord or God, but the God and Lord supreme .... the Lord Himself handing down to His disciples, that He, the Father, is the only God and Lord, who alone is God and ruler of all; it is incumbent on us to follow ... their testimonies to this effect.” (ANF, 1:422, ‘Against Heresies’)
“Such, then, are the first principles of the Gospel: that there is one God, the Maker of this universe; He who was also announced by the prophets ... which proclaim the Father of our Lord Jesus Christ, and ignore any other God or Father except Him.” (ANF, 1:428, ‘Against Heresies’)
“For faith, which has respect to our Master, endures unchangeably, assuring us that there is but one true God, and that we should truly love Him for ever, seeing that He alone is our Father.” (ANF, 1:399-400, ‘Against Heresies’)
“If, for instance, anyone asks, ‘what was God doing before He made the world?’ we reply that the answer to such a question .... remains with God, and it is not proper for us to aim at bringing forward foolish, rash, and blasphemous suppositions [in reply to it] .... For consider all ye who invent such opinions, since the Father Himself is alone called God ... since, moreover, the Scriptures acknowledge Him alone as God” - (ANF, 1:400, ‘Against Heresies’)
Like most, if not all, Ante-Nicene Fathers Irenaeus taught that “Wisdom” speaking at Prov. 8:22-30 is the pre-incarnate Jesus Christ, the Word. In fact, the very trinitarian writers of ANF admit also:
Prov. viii 22-25. This is one of the favourite Messianic quotations of the Fathers, and is considered as the base of the first chapter of St. John’s Gospel. - ANF 1:488, f.n. #10.
Here, then, is what Irenaeus taught about the Son of God, Wisdom, the Word, speaking at Prov. 8:22-25:
‘The Lord {“YHWH” in Hebrew OT manuscripts} created me the beginning of His ways in His work ... before all the hills, He brought me forth ... when He made the foundations of the earth strong, I was with Him preparing [them].’ .... There is therefore one God, who by {through} the Word and Wisdom created and arranged all {other} things. - ANF 1:488.
Tertullian (c. 160-220 A.D.)
Tertullian gave a distinctly subordinate place to the Son. The Son is not eternal. The eternal God became Father when he begot {or ‘generated’ or ‘produced’} the Son, just as he became Creator when he made the world. On this point Tertullian is one with the Apologists. - pp. 112-113, Boer (trinitarian), A Short History of the Early Church, Eerdmans (trinitarian), 1976.
Tertullian, too, like the other Ante-Nicene Fathers, taught that Prov. 8:22-30 relates the words of the Son of God, Christ (speaking as “Wisdom”):
“‘At first the Lord {YHWH} created me as the beginning of His ways, with a view to His own works, before He made the earth, before the mountains were settled; moreover, before all the hills did He beget me;’ that is to say, He created and generated me in His own intelligence.” - ANF, 3:601, ‘Against Praxeas’. (Oldest existing manuscripts from 11th century)
And,
"Scripture in other passages teaches us of the creation of the individual parts. You have Wisdom {the Son of God} saying, ‘But before the depths was I brought forth,’ in order that you may believe that the depths were also ‘brought forth’ - that is, created - just as we create sons also, though we ‘bring them forth.’ It matters not whether the depth {like Wisdom itself} was made or born, so that a beginning be accorded to it" - ANF, 3:495, ‘Against Hermogenes’. (Oldest existing manuscript from early 11th century)
Clement of Alexandria (c. 150-213 A.D.)
Clement of Alexandria (c. 150 - c. 213), wrote, in a discussion of God:
“This discourse respecting God is most difficult to handle. For since the first principle of everything is difficult to find out, the absolutely first and oldest principle, which is the cause of all other things being and having been, is difficult to exhibit. …. No one can rightly express Him wholly. For on account of His greatness He is ranked as the All, and is the Father of the universe. Nor are any parts to be predicated of Him For the One is indivisible.” – pp. 463-4, vol. 2, The Ante-Nicene Fathers [ANF], Eerdmans Publishing, 1989.
Clement, as with most (if not all) of the Ante-Nicene Fathers, also believed and taught that Prov. 8:22-30 presented the words of the Son of God (speaking as “Wisdom”) in his pre-human existence. He wrote:
“Wisdom, which was the first of the creation of God.” (Cf. Rev. 3:14) - ANF 2:465, ‘The Stromata.’
