Remigius of Auxerre
Catena Aurea · Matthäusevangelium 3
In those days came John the Baptist, preaching in the wilderness of Judæa, And saying, Repent ye: for the kingdom of heaven is at hand. For this is he that was spoken of by the Prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make His paths straight.
Though as far as historical fact is concerned, he chose the desert, to be removed from the crowds of people. What the purport of his cry was is insinuated, when he adds, Make ready the way of the Lord.
