The Manners of the Christians:
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... 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. ... As a king sends his son, who is also a king, so sent He Him; as God 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 loving us He sent Him, not as judging us. For He will yet send Him to judge us, and who shall endure His appearing?... 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.
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, ... 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 them that 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.
These Things are Worthy to Be Known and Believed:
I do not speak of things strange to me, nor do I aim at anything inconsistent with right reason; but having been a disciple of the Apostles, I am become a teacher of the Gentiles. I minister the things delivered to me to those that are disciples worthy of the truth. For who that is rightly taught and begotten by the loving Word, would not seek to learn accurately the things which have been clearly shown by the Word to His disciples, to whom the Word being manifested has revealed them, speaking plainly [to them], not understood indeed by the unbelieving, but conversing with the disciples, who, being esteemed faithful by Him, acquired a knowledge of the mysteries of the Father? For which reason He sent the Word, that He might be manifested to the world; and He, being despised by the people [of the Jews], was, when preached by the Apostles, believed on by the Gentiles. This is He who was from the beginning, who appeared as if new, and was found old, and yet who is ever born afresh in the hearts of the saints. This is He who, being from everlasting, is to-day called the Son; through whom the Church is enriched, and grace, widely spread, increases in the saints. furnishing understanding, revealing mysteries, announcing times, rejoicing over the faithful. giving to those that seek, by whom the limits of faith are not broken through, nor the boundaries set by the fathers passed over. Then the fear of the law is chanted, and the grace of the prophets is known, and the faith of the gospels is established, and the tradition of the Apostles is preserved, and the grace of the Church exults; which grace if you grieve not, you shall know those things which the Word teaches, by whom He wills, and when He pleases. For whatever things we are moved to utter by the will of the Word commanding us, we communicate to you with pains, and from a love of the things that have been revealed to us.
The Importance of Knowledge to True Spiritual Life:
When you have read and carefully listened to these things, you shall know what God bestows on such as rightly love Him, being made [as ye are] a paradise of delight, presenting in yourselves a tree bearing all kinds of produce and flourishing well, being adorned with various fruits. For in this place the tree of knowledge and the tree of life have been planted; but it is not the tree of knowledge that destroys-it is disobedience that proves destructive. Nor truly are those words without significance which are written, how God from the beginning planted the tree of life in the midst of paradise, revealing through knowledge the way to life, and when those who were first formed did not use this [knowledge] properly, they were, through the fraud of the Serpent, stripped naked. For neither can life exist without knowledge, nor is knowledge secure without life. Wherefore both were planted close together. The Apostle, perceiving the force [of this conjunction], and blaming that knowledge which, without true doctrine, is admitted to influence life, declares, "Knowledge puffeth up, but love edifieth." For he who thinks he knows anything without true knowledge, and such as is witnessed to by life, knows nothing, but is deceived by the Serpent, as not loving life. But he who combines knowledge with fear, and seeks after life, plants in hope, looking for fruit. Let your heart be your wisdom; and let your life be true knowledge inwardly received. Bearing this tree and displaying its fruit, thou shalt always gather in those things which are desired by God, which the Serpent cannot reach, and to which deception does not approach; nor is Eve then corrupted, but is trusted as a virgin; and salvation is manifested, and the Apostles are filled with understanding, and the Passover of the Lord advances, and the choirs are gathered together, and are arranged in proper order, and the Word rejoices in teaching the saints,-by whom the Father is glorified: to whom be glory for ever. Amen.
