Remigius of Auxerre
Catena Aurea · Matthäusevangelium 13
Hear ye therefore the parable of the sower. When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart. This is he which received seed by the way side. But he that received the seed into stony places, the same is he that heareth the word, and anon with joy receiveth it; Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended. He also that received seed among the thorns is he that heareth the word; and the care of this world, and the deceitfulness of riches, choke the word, and he becometh unfruitful. But he that received seed into the good ground is he that heareth the word, and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty.
The thirty-fold then is borne of him who teaches faith in the Holy Trinity; the sixty-fold of him who enforces the perfection of good works; (for in the number six this world was completed with all its equipments;) (Gen. 2:1) while he bears the hundred-fold who promises eternal life. For the number one hundred passes from the left hand to the right; and by the left hand the present life is denoted, by the right hand the life to come. Otherwise, the seed of the word of God brings forth fruit thirty-fold when it begets good thoughts, sixty-fold when good speech, and an hundred-fold when it brings to the fruit of good works.
