Well, there is a passage in the Didache (2:7) which reads, "thou shalt not hate any man, but some thou shalt confute, concerning some thou shalt pray, and some thou shalt love beyond thine own soul."
Is this referring to the range of relationships we can have with people in general, or just with our "enemies"? For example, if it is toward people in general, it would be saying:
Hate no one.
Prove some wrong.
Pray for some.
Love some beyond your own soul.
If it is toward only our "enemies," then it would be saying,
Do not hate your enemies,
but prove some of your enemies wrong,
pray for some of your enemies,
and love some of your enemies more than yourself.
I am inclined toward the former interpretation. Any thoughts?
