“For a man to love again where he is loved, it is the charity of publicans contracted by mutual profit and good offices; but to love a man's enemies is one of the cunningest points of the law of Christ, and an imitation of the divine nature.”

Hope, Faith, and Love (c. 1786); also known as "The Words of Strength", as translated in The Common School Journal Vol. IX (1847) edited by Horace Mann, p. 386
Context: There are three lessons I would write, —
Three words — as with a burning pen,
In tracings of eternal light
Upon the hearts of men. Have Hope. Though clouds environ now,
And gladness hides her face in scorn,
Put thou the shadow from thy brow, —
No night but hath its morn. Have Faith. Where'er thy bark is driven, —
The calm's disport, the tempest's mirth, —
Know this: God rules the hosts of heaven,
The habitants of earth. Have Love. Not love alone for one,
But men, as man, thy brothers call;
And scatter, like the circling sun,
Thy charities on all. Thus grave these lessons on thy soul, —
Hope, Faith, and Love, — and thou shalt find
Strength when life's surges rudest roll,
Light when thou else wert blind.

1950s, Loving Your Enemies (Christmas 1957)
Context: Forgiveness does not mean ignoring what has been done or putting a false label on an evil act. It means, rather, that the evil act no longer remains as a barrier to the relationship. Forgiveness is a catalyst creating the atmosphere necessary for a fresh start and a new beginning. It is the lifting of a burden or the canceling of a debt. The words "I will forgive you, but never forget what you have done" never explain the real nature of forgiveness. Certainly one can never forget, if that means erasing totally for his mind. But when we forgive, we forget in the sense that the evil deed is no longer a mental block impeding a new relationship. Likewise, we can never say, "I will forgive you, but I won't have anything further to do with you." Forgiveness means reconciliation, a coming together again. Without this, no man can ever love his enemies. The degree to which we are able to forgive determines the degree to which we are able to love our enemies.

"The Truth of Orthodoxy" as translated in Vestnik of the Russian West European Patriarchal Exarchate (1952)
Context: The greater part of Eastern teachers of the Church, from Clement of Alexandria to Maximus the Confessor, were supporters of Apokatastasis, of universal salvation and resurrection. And this is characteristic of (contemporary) Russian religious thought. Orthodox thought has never been suppressed by the idea of Divine justice and it never forgot the idea of Divine love. Chiefly — it did not define man from the point of view of Divine justice but from the idea of transfiguration and Deification of man and cosmos.
