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.
Therefore in heretics and false catholics, it becomes us to abhor, and forbid not the common sacraments in which they are with us, and not against us, but the divisions contrary to peace and truth, wherein they are against us as following not the Lord.
