Catena Aurea · Lukasevangelium 7
And the disciples of John shewed him of all these things. And John calling unto him two of his disciples sent them to Jesus, saying, Art thou he that should come? or look we for another? When the men were come unto him, they said, John Baptist hath sent us unto thee, saying, Art thou he that should come? or look we for another? And in the same hour he cured many of their infirmities and plagues, and of evil spirits; and unto many that were blind he gave sight. Then Jesus answering said unto them, Go your way, and tell John what things ye have seen and heard; how that the blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, to the poor the Gospel is preached. And blessed is he, whosoever shall not be offended in me.
But still these are but slight examples of the testimony to the Lord. The full assurance of faith is the cross of the Lord, His death and burial. Hence He adds, And blessed is he who shall not be offended in me. For the cross may cause offence, even to the elect. But there is no greater testimony than this of a divine person. For there is nothing which seems to be more surpassing the nature of man than that one should offer Himself for the whole world.
