Bede the Venerable
Catena Aurea · Markusevangelium 1
And they went into Capernaum; and straightway on the sabbath day he entered into the synagogue, and taught. And they were astonished at his doctrine: for he taught them as one that had authority, and not as the Scribes.
(ubi sup.) The Scribes themselves taught the people what was written in Moses and the Prophets: but Jesus as the God and Lord of Moses himself, by the freedom of His own will, either added those things which appeared wanting in the Law, or altered things as He preached to the people; as we read in Matthew, It was said to them of old time, but I say unto you. (Mat. 5:27)
