On Christian charity

Give me, O Caesar! give me the earth purged of heretics, and I will give you in exchange the kingdom of heaven. Exterminate with me the heretics, and with you I will exterminate the Persians.

May those who divide Christ be divided with the sword, may they be hewn in pieces, may they be burned alive!

E. Gibbon in the Decline and Fall of the Roman Empire.
