Bede the Venerable
Catena Aurea · Markusevangelium 2
And it came to pass, that he went through the corn fields on the sabbath day; and his disciples began, as they went, to pluck the ears of corn. And the Pharisees said unto him, Behold, why do they on the sabbath day that which is not lawful? And he said unto them, Have ye never read what David did, when he had need, and was an hungred, he, and they that were with him? How he went into the house of God, in the days of Abiathar the High Priest, and did eat the shewbread, which is not lawful to eat but for the priests, and gave also to them which were with him? And he said unto them, The sabbath was made for man, and not man for the sabbath: Therefore the Son of man is Lord also of the sabbath.
(ubi sup.) But in a mystical sense the disciples pass through the corn fields, when the holy doctors look with the care of a pious solicitude upon those whom they have initiated in the faith, and who, it is implied, are hungering for the best of all things, the salvation of men. But to pluck the ears of corn means to snatch men away from the eager desire of earthly things. And to rub with the hands is by examples of virtue to put from the purity of their minds the concupiscence of the flesh, as men do husks. To eat the grains is when a man, cleansed from the filth of vice by the mouths of preachers, is incorporated amongst the members of the Church. Again, fitly are the disciples related to have done this, walking before the faceof the Lord, for it is necessary that the discourse of the doctor should come first, although the grace of visitation from on high, following it, must enlighten the heart of the hearer. And well, on the sabbath-day, for the doctors themselves in preaching labour for the hope of future rest, and teach their hearers to toil over their tasks for the sake of eternal repose.
