Genesis 22:6

4. Righteously also the apostles, being of the race of Abraham, left the ship and their father, and followed the Word. Righteously also do we, possessing the same faith as Abraham, and taking up the cross as Isaac did the wood, follow Him. For in Abraham man had learned beforehand, and had been accustomed to follow the Word of God. For Abraham, according to his faith, followed the command of the Word of God, and with a ready mind delivered up, as a sacrifice to God, his only-begotten and beloved son, in order that God also might be pleased to offer up for all his seed His own beloved and only-begotten Son, as a sacrifice for our redemption.

This “wood,” again, Isaac the son of Abraham personally carried for his own sacrifice, when God had enjoined that he should be made a victim to Himself. But, because these had been mysteries which were being kept for perfect fulfilment in the times of Christ, Isaac, on the one hand, with his “wood,” was reserved, the ram being of fered which was caught by the horns in the bramble; Christ, on the other hand, in His times, carried His “wood” on His own shoulders, adhering to the horns of the cross, with a thorny crown encircling His head. …

Let us cleave then to His blessing, and consider what are the means of possessing it. Let us think over the things which have taken place from the beginning. For what reason was our father Abraham blessed? Was it not because he wrought righteousness and truth through faith? Isaac, with perfect confidence, as if knowing what was to happen, cheerfully yielded himself as a sacrifice. Jacob, through reason of his brother, went forth with humility from his own land, and came to Laban and served him; and there was given to him the sceptre of the twelve tribes of Israel.

11. It is, then, for this reason nowhere written, that the Father is greater than the Holy Spirit, or that the Holy Spirit is less than God the Father, because the creature in which the Holy Spirit was to appear was not taken in the same way as the Son of man was taken, as the form in which the person of the Word of God Himself should be set forth not that He might possess the word of God, as other holy and wise men have possessed it, but “above His fellows;” not certainly that He possessed the word more than they, so as to be of more surpassing wisdom than the rest were, but that He was the very Word Himself. For the word in the flesh is one thing, and the Word made flesh is another; i.e. the word in man is one thing, the Word that is man is another. …

Sarah had lulled Isaac, who as a slave bare the Image of the King his Master on his shoulders, even the sign of His Cross; yea, on his hands were bandages and sufferings, a type of the nails.
