Augustine of Hippo
Catena Aurea · Matthäusevangelium 11
Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.
(Serm. 70. 1.) So then they who with unfearing neck have submitted to the yoke of the Lord endure such hardships and dangers, that they seem to be called not from labour to rest, but from rest to labour. But the Holy Spirit was there who, as the outward man decayed, renewed the inward man day by day, and giving a foretaste of spiritual rest in the rich pleasures of God in the hope of blessedness to come, smoothed all that seemed rough, lightened all that was heavy. Men suffer amputations and burnings, that at the price of sharper pain they may be delivered from torments less but more lasting, as boils or swellings. What storms and dangers will not merchants undergo that they may acquire perishing riches? Even those who love not riches endure the same hardships; but those that love them endure the same, but to them they are not hardships. For love makes right easy, and almost nought all things however dreadful and monstrous. How much more easily then does love do that for true happiness, which avarice does for misery as far as it can?
