If you offer fasting with humility and with mercy, your bones, as Isaiah said, shall be fat, and you shall be like a well-watered garden (cf. Isa. 58:11). So, then, your soul shall grow fat and its virtues also by the spiritual richness of fasting, and your fruits shall be multiplied by the fertility of your mind, so that there may be in you the inebriation of soberness, like that cup of which the Prophet says: 'Your cup which inebriates, how excellent it is' (Ps. 23:5 LXX)!

If you are at Rome live in the Roman style; if you are elsewhere live as they live elsewhere.

A kindness received should be returned with a freer hand.

How far, O rich, do you extend your senseless avarice? Do you intend to be the sole inhabitants of the earth? Why do you drive out the fellow sharers of nature, and claim it all for yourselves? The earth was made for all, rich and poor, in common. Why do you rich claim it as your exclusive right?

Let us, then, sealed by this Trinity, take more diligent heed, lest either levity of character or the deceit of any unfaithfulness unseal the pledge which we have received in our hearts.
