Psalms 16:3

But one man applies less, one more, to learning and training. Wherefore also some have been competent to attain to perfect virtue, and others have attained to a kind of it. And some, on the other hand, through negligence, although in other respects of good dispositions, have turned to the opposite. Now much more is that knowledge which excels all branches of culture in greatness and in truth, most difficult to acquire, and is attained with much toil. “But, as seems, they know not the mysteries of God. For God created man for immortality, and made him an image of His own nature;” according to which nature of Him who knows all, he who is a Gnostic, and righteous, and holy with prudence, hastes to reach the measure of perfect manhood. …

3. “Thou hast proved and visited Mine heart in the night-season” ( ver. 3 ). For this Mine heart hath been proved by the visitation of tribulation. “Thou hast examined Me by fire, and iniquity hath not been found in Me.” Now not night only, in that it is wont to disturb, but fire also, in that it burns, is this tribulation to be called; whereby when I was examined I was found righteous.

And he said not, “Go not after them,” but what is more, Do not admit them into thy mind; which he says also in another place, “I will not mention their names through my lips.” ( Ps. xvi. 4 .) And again, “That my mouth may not talk of the deeds of men.” ( Ps. xvii. 3, 4 .) As yet is this no great virtue; nay, rather, it is indeed great, but not such as this [which is here spoken of]. For what does he say there? He says not; “Talk not of the things of men, neither speak of the things of thy fathers”; but, neither remember them, nor admit them into thy mind. Thou seest to how great a distance he would have us keep away from wickedness. For he that remembers not [a matter] will not think of it, and he that does not think, will not speak of it: and he that does not speak of it, will not do it. …

3. The other saints also, who had a like confidence in God, accepted a like probation with gladness, as Job said, ‘Blessed be the name of the Lord.’ But the Psalmist, ‘Search me, O Lord, and try me: prove my reins and my heart.’ For since, when the strength is proved, it convinceth the foolish, they perceiving the cleansing and the advantage resulting from the divine fire, were not discouraged in trials like these, but they rather delighted in them, suffering no injury at all from the things which happened, but being seen to shine more brightly, like gold from the fire, as he said, who was tried in such a school of discipline as this; ‘Thou hast tried my heart, Thou hast visited me in the night-season; Thou hast proved me, and hast not found iniquity in me, so that my mouth shall not speak of the works of men.’ But those whose actions are not restrained by law, who know of nothing beyond …

7. What measures are they now taking against the Church? For the shiftiness of their originators, shocking; for the apathy of all who are affected by them, pitiable. By a respectable commission the children and grandchildren of Euippius have been summoned from distant regions to Sebasteia, and to them the people have been entrusted. They have taken possession of the altar. They have been made the leaven of that Church. I am persecuted by them as a Homoousiast. Eustathius, who brought the Homoousion in the script from Rome to Tyana, although he was not able to get admitted into their much to be coveted communion, either because they feared, or respected the authority of, the large number of persons who had agreed in condemning him, is now in intimate alliance with them. …
