And they brought unto him also infants, that he would touch them: but when his disciples saw it, they rebuked them.
All Commentaries on Luke 18:15 Go To Luke 18
Ambrose of Milan
AD 397
Why does he say that children are fit for the kingdom of heaven? Perhaps it is because they do not know spitefulness, have not learned to deceive, dare not strike back, neglect to search for wealth, and do not work after honor and ambition…. Childhood is not meant, but rather goodness rivaling childlike simplicity. It is not a virtue to be unable to sin, but to be unwilling to do so and to retain perseverance of will, so that the will imitates childhood and the person imitates nature.
