Bede

We have heard from the Gospel reading [commenting on Lk 2:1-14], dearly beloved brothers, that when the Redeemer of the world, our Lord and God, Jesus Christ, was about to be born into the world, an edict went out from Caesar Augustus, who then held the highest place with respect to worldly reigns. The edict said that the entire world was to be enrolled. We must not suppose that this happened by chance, but we must understand that it was provided through a most certain divinely arranged plan of this same Redeemer of ours. And, indeed, just as in his divinity the Mediator between God and human beings foresaw the mother of whom he willed to be born when he should so will, so also in his humanity he chose the time when he wished for his nativity. Moreover, he himself granted that this time should be such as he willed, namely, that in a calm among the storm of wars a singular tranquillity of unusual peace should cover the whole world.
