Agape Love

“There is, nevertheless, a distinction between them [Eros and Agape]. The love [Agape] which the gospel demands is justified and validated only transcendentally. We are asked to love our enemies that we may be children of our Father in Heaven. An attitude of spirit is enjoined without any prudential or selfish consideration. We are not told to love our enemies because in that case they will love us in return. The love that is asked of us does not move on the plane of emotion or desire.

Such a love is not easily achieved. In a sense no one ever perfectly achieves it. But it is, at least, no psychological absurdity. It does not demand that we should be emotionally attached [Eros] to someone with whom we are in conflict. It does demand that we should desire the good of our enemy. If achieved, it purges us of hatred; for hatred always has an egoistic root….

The love that the New Testament defines as AGAPE is spiritually difficult; but it is psychologically possible….”
