Bede the Venerable
Catena Aurea · Markusevangelium 10
And they brought young children to him, that he should touch them: and his disciples rebuked those that brought them. But when Jesus saw it, he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God. Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein. And he took them up in his arms, put his hands upon them, and blessed them.
(ubi sup.) That is, if ye have not innocence and purity of mind like that of children, ye cannot enter into the kingdom of heaven. Or else, we are ordered to receive the kingdom of God, that is, the doctrine of the Gospel, as a little child, because as a child, when he is taught, does not contradict his teachers, nor put together reasonings and words against them, but receives with faith what they teach, and obeys them with awe, so we also are to receive the word of the Lord with simple obedience, and without any gainsaying. It goes on: And he took them up in his arms, put his hands upon them, and blessed them.
