Bede the Venerable
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.
But Christ would have lost the fruit of His Passion had He not been the Truth of the resurrection, therefore it is said, And to rise from the dead. He then after having commended to them the truth of the body, commends the unity of the Church, adding, And that repentance and remission of sins should be preached in his name among all nations.
