Catena Aurea · Matthäusevangelium 19
Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven. And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved? But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.
(Mor. xxxv. 16.) Or, by the rich man He intends any one who is proud, by the camel he denotes the right humility. The camel passed through the needle’s eye, when our Redeemer through the narrow way of suffering entered in to the taking upon Him death; for that passion was as a needle which pricked the body with pain. But the camel enters the needle’s eye easier than the rich man enters the kingdom of heaven; because if He had not first shewn us by His passion the form of His humility, our proud stiffness would never have bent itself to His lowliness.
