The example of the good Samaritan shows that we must not abandon those in whom even the faintest amount of faith is still alive.
-St. Ambrose of Milan, Two Books of St. Ambrose, Bishop of Milan, Concerning Repentance, Chapter 11

But you cannot be a neighbour unless you have compassion on him; for no one can be called a neighbour unless he have healed, not killed, another. But if you wish to be called a neighbour, Christ says to you: "Go and do likewise."
-St. Ambrose of Milan, Two Books of St. Ambrose, Bishop of Milan, Concerning Repentance, Chapter 11

Godly love cannot be perfect unless a man love his neighbor also. Under which name must be included not only those who are connected with us by friendship or neighborhood, but absolutely all men, with whom we have a common nature, whether they be foes or allies, slaves or free.
-St. Gregory the Dialogist, Sermon 12, On the Fast, 6th century
