In this short post I will share two 2nd-3rd century testimonies to the absolute, essential Deity of Christ and his personal distinction from God the Father. All emphasis shall be mine.

Chapter 7. The manifestation of Christ
For, as I said, this was no mere earthly invention which was delivered to them, nor is it a mere human system of opinion, which they judge it right to preserve so carefully, nor has a dispensation of mere human mysteries been committed to them, but truly God Himself, who is almighty, the Creator of all things, and invisible, has sent from heaven, and placed among men, [Him who is] the truth, and the holy and incomprehensible Word, and has firmly established Him in their hearts. He did not, as one might have imagined, send to men any servant, or angel, or ruler, or any one of those who bear sway over earthly things, or one of those to whom the government of things in the heavens has been entrusted, but THE VERY CREATOR AND FASHIONER of all things — BY WHOM He made the heavens — BY WHOM he enclosed the sea within its proper bounds — whose ordinances all the stars faithfully observe — FROM WHOM the sun has received the measure of his daily course to be observed — WHOM the moon obeys, being commanded to shine in the night, and whom the stars also obey, following the moon in her course; BY WHOM all things have been arranged, and placed within their proper limits, and TO WHOM all are subject — the heavens and the things that are therein, the earth and the things that are therein, the sea and the things that are therein — fire, air, and the abyss — the things which are in the heights, the things which are in the depths, and the things which lie between. This [messenger] He sent to them. Was it then, as one might conceive, for the purpose of exercising tyranny, or of inspiring fear and terror? By no means, but under the influence of clemency and meekness. As a king sends his son, who is also a king, so sent He Him; AS GOD He sent Him; as to men He sent Him; as a Saviour He sent Him, and as seeking to persuade, not to compel us; for violence has no place in the character of God. As calling us He sent Him, not as vengefully pursuing us; as loving us He sent Him, not as judging us. For He will yet send Him to judge us, and who shall endure His appearing? Malachi 3:2…
Do you not see them exposed to wild beasts, that they may be persuaded to deny the Lord, and yet not overcome? Do you not see that the more of them are punished, the greater becomes the number of the rest? This does not seem to be the work of man: this is the power of God; these are the evidences of His manifestation.
Chapter 8. The miserable state of men before the coming of the Word
For, who of men at all understood before His coming what God is? Do you accept of the vain and silly doctrines of those who are deemed trustworthy philosophers? Of whom some said that fire was God, calling that God to which they themselves were by and by to come; and some water; and others some other of the elements formed by God. But if any one of these theories be worthy of approbation, every one of the rest of created things might also be declared to be God. But such declarations are simply the startling and erroneous utterances of deceivers; and no man has either seen Him, or made Him known, but He has revealed Himself. And He has manifested Himself through faith, to which alone it is given to behold God. For God, the Lord and Fashioner of all things, who made all things, and assigned them their several positions, proved Himself not merely a friend of mankind, but also long-suffering [in His dealings with them]. Yea, He was always of such a character, and still is, and will ever be, kind and good, and free from wrath, and true, and the only one who is [absolutely] good; Matthew 19:17 and He formed in His mind a great and unspeakable conception, which He communicated to His Son alone. As long, then, as He held and preserved His own wise counsel in concealment, He appeared to neglect us, and to have no care over us. But after He revealed and laid open, through His beloved Son, the things which had been prepared from the beginning, He conferred every blessing all at once upon us, so that we should both share in His benefits, and see and be active [in His service]. Who of us would ever have expected these things? He was aware, then, of all things in His own mind, along with His Son, according to the relation subsisting between them.
Chapter 9. Why the Son was sent so late
As long then as the former time endured, He permitted us to be borne along by unruly impulses, being drawn away by the desire of pleasure and various lusts. This was not that He at all delighted in our sins, but that He simply endured them; nor that He approved the time of working iniquity which then was, but that He sought to form a mind conscious of righteousness, so that being convinced in that time of our unworthiness of attaining life through our own works, it should now, through the kindness of God, be vouchsafed to us; and having made it manifest that in ourselves we were unable to enter into the kingdom of God, we might through the power of God be made able. But when our wickedness had reached its height, and it had been clearly shown that its reward, punishment and death, was impending over us; and when the time had come which God had before appointed for manifesting His own kindness and power, how the one love of God, through exceeding regard for men, did not regard us with hatred, nor thrust us away, nor remember our iniquity against us, but showed great long-suffering, and bore with us, He Himself took on Him the burden of our iniquities, He gave His own Son as a ransom for us, the holy One for transgressors, the blameless One for the wicked, the righteous One for the unrighteous, the incorruptible One for the corruptible, the immortal One for those who are mortal. For what other thing was capable of covering our sins than His righteousness? By what other one was it possible that we, the wicked and ungodly, could be justified, than by the only Son of God? O sweet exchange! O unsearchable operation! O benefits surpassing all expectation! That the wickedness of many should be hid in a single righteous One, and that the righteousness of One should justify many transgressors! Having therefore convinced us in the former time that our nature was unable to attain to life, and having now revealed the Saviour who is able to save even those things which it was [formerly] impossible to save, by both these facts He desired to lead us to trust in His kindness, to esteem Him our Nourisher, Father, Teacher, Counsellor, Healer, our Wisdom, Light, Honour, Glory, Power, and Life, so that we should not be anxious concerning clothing and food.
Fragments of Melito of Sardis

On Faith.
We have collected together extracts from the Law and the Prophets relating to those things which have Been declared concerning our Lord Jesus Christ, that we may prove to your love that this Being is perfect reason, the Word of God; He who was begotten before the light; He who is CREATOR together with the Father; He who is the Fashioner of man; He who is all in all; He who among the patriarchs is Patriarch; He who in the law is the Law; among the priests, Chief Priest; among kings, the Ruler; among prophets, the Prophet; among the angels, Archangel; in the voice of the preacher, the Word; among spirits, the Spirit; in the Father, the Son; in God, GOD; King for ever and ever. For this is He who was pilot to Noah; He who was guide to Abraham; He who was bound with Isaac; He who was in exile with Jacob; He who was sold with Joseph; He who was captain of the host with Moses; He who was the divider of the inheritance with Jesus the son of Nun; He who in David and the prophets announced His own sufferings; He who put on a bodily form in the Virgin; He who was born in Bethlehem; He who was wrapped in swaddling-clothes in the manger; He who was seen by the shepherds; He who was glorified by the angels; He who was worshipped by the Magi; He who was pointed out by John; He who gathered together the apostles; He who preached the kingdom; He who cured the lame; He who gave light to the blind; He who raised the dead; He who appeared in the temple; He who was not believed on by the people; He who was betrayed by Judas; He who was apprehended by the priests; He who was condemned by Pilate; He who was pierced in the flesh; He who was hanged on the tree; He who was buried in the earth; He who rose from the place of the dead; He who appeared to the apostles; He who was carried up to heaven; He who is seated at the right hand of the Father; He who is the repose of those that are departed; the recoverer of those that are lost; the light of those that are in darkness; the deliverer of those that are captive; the guide of those that go astray; the asylum of the afflicted; the bridegroom of the Church; the charioteer of the cherubim; the captain of the angels; GOD WHO IS FROM GOD; the Son who is from the Father; Jesus Christ the King for evermore. Amen.
This is He who took a bodily form in the Virgin, and was hanged upon the tree, and was buried within the earth, and suffered not dissolution; He who rose from the place of the dead, and raised up men from the earth-from the grave below to the height of heaven. This is the Lamb that was slain; this is the Lamb that opened not His mouth. This is He who was born of Mary, fair sheep of the fold. This is He that was taken from the flock, and was led to the slaughter, and was slain in the evening, and was buried at night; He who had no bone of Him broken on the tree; He who suffered not dissolution within the earth; He who rose from the place of the dead, and raised up the race of Adam from the grave below, This is He who was put to death. And where was He put to death? In the midst of Jerusalem. By whom? By Israel: became He cured their lame, and cleansed their lepers, and gave light to their blind, and raised their dead! This was the cause of His death. Thou, O Israel, wast giving commands, and He was being crucified; thou wast rejoicing, and He was being buried; thou wast reclining on a soft couch, and He was watching in the grave and the shroud. O Israel, transgressor of the law, why hast thou committed this new iniquity, subjecting the Lord to new sufferings-thine own Lord, Him who fashioned thee, Him-who made thee, Him who honoured thee, who called thee Israel? But thou hast not been found to be Israel: for thou hast not seen God, nor understood the Lord. Thou hast not known, O Israel, that this was the first-born of God, who was begotten before the sun, who made the light to shine forth, who lighted up the day, who separated the darkness, who fixed the first foundations, who poised the earth, who collected the ocean, who stretched out the firmament, who adorned the world. Bitter were thy nails, and sharp; bitter thy tongue, which thou didst whet; bitter was Judas, to whom thou gavest hire; bitter thy false witnesses, whom thou stirredst up; bitter thy gall, which thou preparedst; bitter thy vinegar, which thou madest; bitter thy hands, filled with blood. Thou slewest thy Lord, and He was lifted up upon the tree; and an inscription was fixed above, to show who He was that was slain.
And who was this? (that which we shall not say is too shocking to hear, and that which we shall say is very dreadful: nevertheless hearken, and tremble.) It was He because of whom the earth quaked. He that hung up the earth in space was Himself hanged up; He that fixed the heavens was fixed with nails; He that bore up the earth was borne up on a tree; the Lord of all was subjected to ignominy in a naked body-GOD PUT TO DEATH! the King of Israel slain with Israel’s right hand! Alas for the new wickedness of the new murder! The Lord was exposed with naked body: He was not deemed worthy even of covering; and, in order that He might not be seen, the luminaries turned away, and the day became darkened because THEY SLEW GOD, who hung naked on the tree. It was not the body of our Lord that the luminaries covered with darkness when they set, but the eyes of men. For, because the people quaked not, the earth quaked; because they were not affrighted, the earth was affrighted. Thou smotest thy Lord: thou also hast been smitten upon the earth. And thou indeed liest dead; but He is risen from the place of the dead, and ascended to the height of heaven, having suffered for the sake of those who suffer, and having been bound for the sake of Adam’s race which was imprisoned, and having been judged for the sake of him who was condemned, and having been buried for the sake of him who was buried.
And further on: –This is He who made the heaven and the earth, and in the beginning, together with the Father, fashioned man; who was announced by means of the law and the prophets; who put on a bodily form in the Virgin; who was hanged upon the tree; who was buried in the earth; who rose from the place of the dead, and ascended to the height of heaven, and sitteth on the right hand of the Father.
