Cain Goes Out from the Face of the Lord and Judas Goes to His Own Place
Old Testament: Genesis 4:13, 16
And Cain said to the Lord: My iniquity is greater than that I may deserve pardon... And Cain went out from the face of the Lord, and dwelt as a fugitive on the earth, at the east side of Eden.
Old Testament, also: Genesis 4:12
When thou shalt till it, it shall not yield to thee its fruit: a fugitive and a vagabond shalt thou be upon the earth.
New Testament: Acts 1:25
To take the place of this ministry and apostleship, from which Judas hath by transgression fallen, that he might go to his own place.
The connection
Both men betray someone inside the closest circle they have, a brother and a master at table, and both are confronted directly, Cain with where is thy brother Abel, and Judas with he that dippeth his hand with me in the dish. Both then admit their guilt. Cain says my iniquity is greater than that I may deserve pardon, and Judas says I have sinned in betraying innocent blood. Neither admission is repentance, because both are addressed to the size of the offence rather than to the mercy of the one offended. What follows in each case is described with the same strange restraint. God's sentence is that Cain shall be a fugitive and a vagabond, yet when it is carried out Scripture says only that he went out from the face of the Lord and dwelt as a fugitive, so that the sentence is narrated as a road he walks. Luke uses the same kind of language for Judas, that he might go to his own place, declining to name what that place is and putting it in the possessive, as though the man had made it. The gravity of both texts is in what they refuse to say. Neither narrator shows God driving the man out. Each describes the man going.
Moral sense
Admitting the full weight of what you have done is not yet contrition, and can be its counterfeit. Cain and Judas both measured their sin against themselves rather than against mercy, which is the difference between the sorrow that works penance and the sorrow of the world that worketh death.
Anagogical sense
The last word on both men is a place rather than a verdict, and in Judas's case it is called his own, which is how Scripture speaks of a separation that is chosen and not merely suffered.
The Fathers
St Ambrose, Concerning Repentance, Book II, ch. 4, sect. 27, on where the confession was taken: “For I suppose that even Judas might through the exceeding mercy of God not have been shut out from forgiveness, if he had expressed his sorrow not before the Jews but before Christ.” St John Chrysostom, Homilies on the Acts of the Apostles, Homily 3, on the field bought with the betrayal money: “the reward of the treachery was made itself the herald of the punishment.”
Warrant
Acts 1:25 does not mention Cain, and no patristic source has been located that reads Judas through Cain directly; the pairing of the two men as a single genealogy of betrayal belongs to later medieval legend rather than to the Fathers. Jude 1:11 does establish the way of Cain as a named New Testament pattern of ruin, applying it to false teachers rather than to Judas. The link here therefore rests on the shared structure of the two accounts, betrayal within the closest circle, a confession of guilt that stops short of seeking pardon, and a departure narrated as the man's own going rather than as an expulsion, together with the unusual possessive in the phrase his own place. Ambrose supplies the reading of the New Testament half, that what ruined Judas was not the size of his sin but the direction of his sorrow.
