Rabanus Maurus
Catena Aurea · Matthäusevangelium 13
The same day went Jesus out of the house, and sat by the sea side. And great multitudes were gathered together unto him, so that he went into a ship, and sat; and the whole multitude stood on the shore. And he spake many things unto them in parables, saying, Behold, a sower went forth to sow; And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up: Some fell upon stony places, where they had not much earth: and forthwith they sprung up, because they had no deepness of earth: And when the sun was up, they were scorched; and because they had no root, they withered away. And some fell among thorns; and the thorns sprung up, and choked them: But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold. Who hath ears to hear, let him hear.
But those things which He silently left to our understanding, should be shortly noticed. The wayside is the mind trodden and hardened by the continual passage of evil thoughts; the rock, the hardness of the self-willed mind; the good soil, the gentleness of the obedient mind, the sun, the heat of a raging persecution. The depth of soil, is the honesty of a mind trained by heavenly discipline. But in thus expounding them we should add, that the same things are not always put in one and the same allegorical signification.
