Patristic Wisdom: Looking to Palm Sunday

Now the Feast of Unleavened Bread drew near, which is called Passover. And the chief priests and the scribes sought how they might kill Him, for they feared the people. Then Satan entered Judas, surnamed Iscariot, who was numbered among the twelve. So he went his way and conferred with the chief priests and captains, how he might betray Him to them. And they were glad, and agreed to give him money. So he promised and sought opportunity to betray Him to them in the absence of the multitude. (Luke 22:1–6)

But let us see the course of the devil’s malice, and what was the result of his crafty designs against Him. He had then implanted in the chiefs of the synagogue of the Jews envy against Christ, which proceeded even to murder. For always, so to speak, this malady tends to the guilt of murder. Such, at least, is the natural course of this vice: so it was with Cain and Abel; so plainly it was in the case of Joseph and his brethren; and therefore the divine Paul also very clearly makes these sins neighbors, so to speak, of one another, and akin: for he spoke of some as “full of envy, murder.” They sought therefore to slay Jesus, at the instigation of Satan, who had implanted this wickedness in them, and who also was their captain in their wicked enterprises.... And what was the contrivance of this many-headed serpent? “He entered, it says, into Judas Iscariot, who was one of the twelve.”... And Satan, being crafty in working evil, whenever he would gain possession of any man’s soul, does not attack him by means of vice generally, but searches out rather that particular passion which has power over him, and by its means makes him his prey. As he knew therefore that he was covetous, he leads him to the Pharisees and captains; and to them he promised that he would betray his teacher. And they purchase the treachery, or rather their own destruction, with sacred money. Oh! what tears could suffice, either for him who betrayed Jesus for hire, or for those who hired him, and purchased with consecrated money a guilty murder! What darkness had come upon the soul of him who received the bribe! For a little silver, he lost heaven.
