Isaias 6:8

“Moreover, in the book of Exodus we have also perceived that the name of God Himself which, He says, was not revealed to Abraham or to Jacob, was Jesus, and was declared mysteriously through Moses. Thus it is written: ‘And the Lord spake to Moses, Say to this people, Behold, I send My angel before thy face, to keep thee in the way, to bring thee into the land which I have prepared for thee. Give heed to Him, and obey Him; do not disobey Him. For He will not draw back from you; for My name is in Him.’ Now understand that He who led your fathers into the land is called by this name Jesus, and first called Auses (Oshea). For if you shall understand this, you shall likewise perceive that the name of Him who said to Moses, ‘for My name is in Him,’ was Jesus. For, indeed, He was also called Israel, and Jacob’s name was changed to this also. …

“And spake of Him.” What spake he? “I saw the Lord sitting upon a high throne” ( Isa. vi. 1 ), and what follows. Therefore he there calleth “glory,” that vision, the smoke, the hearing unutterable Mysteries, the beholding the Seraphim, the lightning which leaped from the throne, against which those powers could not look. “And spake of Him.” What said he? That he heard a voice, saying, “Whom shall I send? who shall go? And I said, Here am I, send me. And He said, Ye shall hear with your ears, and shall not understand, and seeing ye shall see, and not perceive.” ( Isa. vi. 8, 10 .) For,

For whereas man sinned, and is fallen, and by his fall all things are in confusion: death prevailed from Adam to Moses (cf. Rom. v. 14 ), the earth was cursed, Hades was opened, Paradise shut, Heaven offended, man, lastly, corrupted and brutalised (cf. Ps. xlix. 12 ), while the devil was exulting against us; then God, in His loving-kindness, not willing man made in His own image to perish, said, ‘Whom shall I send, and who will go?’ ( Isa. vi. 8 ). But while all held their peace, the Son said, ‘Here am I, send Me.’ And then it was that, saying ‘Go Thou,’ He ‘delivered’ to Him man, that the Word Himself might be made Flesh, and by taking the Flesh, restore it wholly. …

114. I resort once again to history, and on considering the men of best repute in ancient days, who were ever preferred by grace to the office of ruler or prophet, I discover that some readily complied with the call, others deprecated the gift, and that neither those who drew back were blamed for timidity, nor those who came forward for eagerness. The former stood in awe of the greatness of the ministry, the latter trustfully obeyed Him Who called them. Aaron was eager, but Moses resisted, Isaiah readily submitted, but Jeremiah was afraid of his youth, and did not venture to prophesy until he had received from God a promise and power beyond his years.

Although sometimes some laudably desire the office of preaching, yet others are as laudably drawn to it by compulsion; as we plainly perceive, if we consider the conduct of two prophets, one of whom offered himself of his own accord to be sent to preach, yet the other in fear refused to go. For Isaiah, when the Lord asked whom He should send, offered himself of his own accord, saying, Here I am; send me ( Isai. vi. 8 ). But Jeremiah is sent, yet humbly pleads that he should not be sent, saying, Ah, Lord God ! behold I cannot speak: for I am a child ( Jer. i. 6 ). Lo, from these two men different voices proceeded outwardly, but they flowed from the same fountain of love. For there are two precepts of charity; the love of God and of our neighbour. …

We have received with becoming charity our common sons, George the presbyter and Theodore your deacon; and we rejoice that you have passed from the care of ecclesiastical business to the government of souls, since, according to the voice of the Truth, He that is faithful in a little will be faithful also in much ( Luke xvi. 10 ). And to the servant who administers well it is said, Because thou hast been faithful over a few things, I will make thee ruler over many things ( Matth. xxv. 23 ); to whom also it is presently said further with respect to eternal retribution, Enter thou into the joy of thy Lord . Now you say in your letter that you had exceedingly wished for rest. But in this you shew that you have fitly assumed pastoral responsibility, since, as a place of rule should be denied to those who covet it, so it should be offered to those who fly from it. …
