Bede the Venerable
Catena Aurea · Lukasevangelium 2
And it came to pass in those days, that there went out a decree from Cæsar Augustus, that all the world should be taxed. (And this taxing was first made when Cyrenius was governor of Syria.) And all went to be taxed, every one into his own city. And Joseph also went up from Galilee, out of the city of Nazareth, into Judæa, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:) To be taxed with Mary his espoused wife, being great with child.
The Son of God, about to be born in the flesh, as by His birth of a virgin He shewed that the grace of virginity was most pleasing in His sight, is therefore begotten in the most peaceful time of the world, because He taught men to seek peace, and condescends to visit those who follow it. But there could be no greater sign of peace than for the whole world to be brought together under one taxing, while its ruler Augustus reigned with so great peace for the twelve years, about the time of our Lord’s nativity, that war having been quelled throughout the whole world, there seemed to be a literal fulfilment of the Prophet’s prediction, They shall beat their swords into ploughshares, &c.
