Exodus 34:6

8. Inasmuch, then, as the Spirit of God pointed out by the prophets things to come, forming and adapting us beforehand for the purpose of our being made subject to God, but it was still a future thing that man, through the good pleasure of the Holy Spirit, should see [God], it necessarily behoved those through whose instrumentality future things were announced, to see God, whom they intimated as to be seen by men; in order that God, and the Son of God, and the Son, and the Father, should not only be prophetically announced, but that He should also be seen by all His members who are sanctified and instructed in the things of God, that man might be disciplined beforehand and previously exercised for a reception into that glory which shall afterwards be revealed in those who love God. …

“But,” say they, “God is ‘good,’ and ‘most good,’ and ‘pitiful-hearted,’ and ‘a pitier,’ and ‘abundant in pitiful-heartedness,’ which He holds ‘dearer than all sacrifice,’ ‘not thinking the sinner’s death of so much worth as his repentance’, ‘a Saviour of all men, most of all of believers.’ And so it will be becoming for ‘the sons of God’ too to be ‘pitiful-hearted’ and ‘peacemakers;’ ‘giving in their turn just as Christ withal hath given to us;’ ‘not judging, that we be not judged.’ For ‘to his own lord a man standeth or falleth; who art thou, to judge another’s servant?’ ‘Remit, and remission shall be made to thee.’” Such and so great futilities of theirs wherewith they flatter God and pander to themselves, effeminating rather than invigorating discipline, with how cogent and contrary (arguments) are we for our part able to rebut, (arguments) which set before us warningly the “severity …

On the other hand, he whose “heart” was habitually found “lifted up” rather than fattened up, who in forty days and as many nights maintained a fast above the power of human nature, while spiritual faith subministered strength (to his body), both saw with his eyes God’s glory, and heard with his ears God’s voice, and understood with his heart God’s law: while He taught him even then (by experience) that man liveth not upon bread alone, but upon every word of God; in that the People, though fatter than he, could not constantly contemplate even Moses himself, fed as he had been upon God, nor his leanness, sated as it had been with His glory! Deservedly, therefore, even while in the flesh, did the Lord show Himself to him, the colleague of His own fasts, no less than to Elijah. …

14. Therefore we ought to believe that God is good, eternal, perfect, almighty, and true, such as we find Him in the Law and the Prophets, and the rest of the holy Scriptures, for otherwise there is no God. For He Who is God cannot but be good, seeing that fulness of goodness is of the nature of God: nor can God, Who made time, be in time; nor, again, can God be imperfect, for a lesser being is plainly imperfect, seeing that it lacks somewhat whereby it could be made equal to a greater. This, then, is the teaching of our faith, that God is not evil, that with God nothing is impossible, that God exists not in time, that God is beneath no being. If I am in error, let my adversaries prove it.
