Eusebius of Caesarea
Catena Aurea · Lukasevangelium 24
Then opened he their understanding, that they might understand the Scriptures, And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
For it was said, Ask of me, and I will give thee the heathen for thine inheritance. (Ps. 2:8.) But it was necessary that those who were converted from the Gentiles should be purged from a certain stain and defilement through His virtue, being as it were corrupted by the evil of the worship of devils, and as lately converted from an abominable and unchaste life. And therefore He says that it behoves that first repentance should be preached, but next, remission of sins, to all nations. For to those who first shewed repentance for their sins, by His saving grace He granted pardon of their transgression, for whom also He endured death.
