• 150 AD Justin Martyr "The Father of the universe has a Son, who also being the first begotten Word of God, is even God." (Justin Martyr, First Apology, ch 63)
150 AD Justin Martyr "Therefore these words testify explicitly that He [Christ] is witnessed to by Him who established these things, as deserving to be worshipped, as God and as Christ." - Dialogue with Trypho, ch. 63.
• 190 AD Clement Of Alexandria [note: Clement NEVER calls Jesus a creature.] "There was then, a Word importing an unbeginning eternity; as also the Word itself, that is, the Son of God, who being, by equality of substance, one with the Father, is eternal and uncreated." (Fragments, Part I, section III) "that so great a work was accomplished in so brief a space by the Lord, who, though despised as to appearance, was in reality adored, the expiator of sin, the Saviour, the clement, the Divine Word, He that is truly most manifest Deity, He that is made equal to the Lord of the universe; because He was His Son, and the Word was in God, not disbelieved in by all when He was first preached, nor altogether unknown when, assuming the character of man, and fashioning Himself in flesh, He enacted the drama of human salvation: for He was a true champion and a fellow-champion with [ie. God among creatures, not that Jesus is classed as a creature] the creature." (Exhortations, Chap 10)
• 190 AD Clement Of Alexandria "I understand nothing else than the Holy Trinity to be meant; for the third is the Holy Spirit, and the Son is the second, by whom all things were made according to the will of the Father." (Stromata, Book V, ch. 14)
• 190 AD Clement Of Alexandria "When [John] says: 'What was from the beginning [1 John 1:1],' he touches upon the generation without beginning of the Son, who is co-equal with the Father. 'Was,' therefore, is indicative of an eternity without a beginning, just as the Word Himself, that is the Son, being one with the Father in regard to equality of substance, is eternal and uncreated. That the word always existed is signified by the saying: 'In the beginning was the Word' [John 1:1]." (fragment in Eusebius History, Bk 6 Ch 14; Jurgens, p. 188)
• 200 AD Tertullian "All the Scriptures give clear proof of the Trinity, and it is from these that our principle is deduced...the distinction of the Trinity is quite clearly displayed." (Against Praxeas, ch 11)
• 200 AD Tertullian "The origins of both his substances display him as man and as God: from the one, born, and from the other, not born" (The Flesh of Christ, 5:6-7).
• 200 AD Tertullian "[God speaks in the plural ‘Let us make man in our image’] because already there was attached to Him his Son, a second person, his own Word, and a third, the Spirit in the Word....one substance in three coherent persons. He was at once the Father, the Son, and the Spirit." (Against Praxeas, ch 12)
• 200 AD Tertullian "Thus the connection of the Father in the Son, and of the Son in the Paraclete, produces three coherent Persons, who are yet distinct One from Another. These Three are, one essence, not one Person, as it is said, 'I and my Father are One' [John 10:30], in respect of unity of Being not singularity of number" (Against Praxeas, 25)
• 200 AD Tertullian "As if in this way also one were not All, in that All are of One, by unity (that is) of substance; while the mystery of the dispensation is still guarded, which distributes the Unity into a Trinity, placing in their order the three Persons — the Father, the Son, and the Holy Ghost: three, however, not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost." (Against Praxeas, by Tertullian)
200 AD Tertullian "[W]hen God says, 'Let there be light' [Gen. 1:3], this is the perfect nativity of the Word, while he is proceeding from God. . . . Thus, the Father makes him equal to himself, and the Son, by proceeding from him, was made the first-begotten, since he was begotten before all things, and the only-begotten, because he alone was begotten of God, in a manner peculiar to himself, from the womb of his own heart, to which even the Father himself gives witness: 'My heart has poured forth my finest Word' [Ps. 45:1Against Praxeas 7:1).
