1. Chapter 1

A Homily delivered on the Saturday before the Second Sunday in Lent — on the Transfiguration, S. Matthew 17:1-13

The Gospel lesson, dearly-beloved, which has reached the inner hearing of our minds through our bodily ears, calls us to the understanding of a great mystery, to which we shall by the help of God's grace the better attain, if we turn our attention to what is narrated just before.

The Saviour of mankind, Jesus Christ, in founding that faith, which recalls the wicked to righteousness and the dead to life, used to instruct His disciples by admonitory teaching and by miraculous acts to the end that He, the Christ, might be believed to be at once the Only-begotten of God and the Son of Man. For the one without the other was of no avail to salvation, and it was equally dangerous to have believed the Lord Jesus Christ to be either only God without manhood, or only man without Godhead, since both had equally to be confessed, because just as true manhood existed in His Godhead, so true Godhead existed in His Manhood. To strengthen, therefore, their most wholesome knowledge of this belief, the Lord had asked His disciples, among the various opinions of others, what they themselves believed, or thought about Him: whereat the Apostle Peter, by the revelation of the most High Father passing beyond things corporeal and surmounting things human by the eyes of his mind, saw Him to be Son of the living God, and acknowledged the glory of the Godhead, because he looked not at the substance of His flesh and blood alone; and with this lofty faith Christ was so well pleased that he received the fullness of blessing, and was endued with the holy firmness of the inviolable Rock on which the Church should be built and conquer the gates of hell and the laws of death, so that, in loosing or binding the petitions of any whatsoever, only that should be ratified in heaven which had been settled by the judgment of Peter.

But this exalted and highly-praised understanding, dearly-beloved, had also to be instructed on the mystery of Christ's lower substance, lest the Apostle's faith, being raised to the glory of confessing the Deity in Christ, should deem the reception of our weakness unworthy of the impassible God, and incongruous, and should believe the human nature to be so glorified in Him as to be incapable of suffering punishment, or being dissolved in death. And, therefore, when the Lord said that He must go to Jerusalem, and suffer many things from the elders and scribes and chief of the priests, and the third day rise again, the blessed Peter who, being illumined with light from above, was burning with the heat of his confession, rejected their mocking insults and the disgrace of the most cruel death, with, as he thought, a loyal and outspoken contempt, but was checked by a kindly rebuke from Jesus and animated with the desire to share His suffering. For the Saviour's exhortation that followed, instilled and taught this, that they who wished to follow Him s
