The Epistle of Mathetes to Diognetus (Excerpt)

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 the Gift of Knowledge of the Heart

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.
