Remigius of Auxerre
Catena Aurea · Matthäusevangelium 4
And Jesus went about all Galilee, teaching in their synagogues, and preaching the Gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people. And His fame went throughout all Syria: and they brought unto Him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and He healed them. And there followed Him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judæa, and from beyond Jordan.
That they should not preach error nor fable, but sound doctrine, is inculcated in the words, preaching the Gospel of the kingdom. ‘Teaching’ and ‘preaching’ differ; teaching refers to things present, preaching to things to come; He taught present commandments and preached future promises.
