Bede the Venerable
Catena Aurea · Lukasevangelium 9
Then there arose a reasoning among them, which of them should be greatest. And Jesus, perceiving the thought of their heart, took a child, and set him by him, And said unto them, Whosoever shall receive this child in my name receiveth me: and whosoever shall receive me receiveth him that sent me: for he that is least among you all, the same shall be great. And John answered and said, Master, we saw one casting out devils in thy name; and we forbad him, because he followeth not with us. And Jesus said unto him, Forbid him not: for he that is not against us is for us.
Now herein He either teaches, that the poor of Christ are to be received by those who wish to be greater simply for His honour, or He persuades men that they are children in malice. Hence when He said, Whoever shall receive that child, he adds, in my name; that in truth they may pursue with diligence and reason for Christ’s name that form of virtue which the child observes, with only nature for its guide. But because He also teaches that He is received in the child, and He Himself was born unto us a child; lest it should be thought that this was all which was seen, He subjoined, And whoever shall receive me, receiveth him that sent me; wishing verily to be believed, that as was the Father, such and so great was He.
