The theology of the Alexandrian school sometimes leave you scratching your head, but here’s a good observation on the mercy of God from Titus Flavius Clemens, aka Clement of Alexandria (c 150 – c 215):
But God has no natural relation to us, as the authors of the heresies will have it; neither on the supposition of His having formed us from matter; since the former did not exist at all, and the latter is totally distinct from God, unless we shall dare to say that we are a part of Him, and of the same essence as God.
And I know not how one, who knows God, can bear to hear this when he looks to our life, and sees in what evils we are involved. . . .
But God being by nature rich in pity, in consequence of His own goodness, cares for us, though neither portions of Himself, nor by nature His children. And this is the greatest proof of the goodness of God: that such being our relation to Him, and being by nature wholly estranged, He nevertheless cares for us. For the affection in animals to their progeny is natural, and the friendship of kindred minds is the result of intimacy.
But the mercy of God is rich towards us, who are in no respect related to Him; I say either in our essence or nature, or in the peculiar energy of our essence, but only in our being the work of His will.
And he who willingly, with discipline and teaching, accepts the knowledge of the truth, He calls to adoption, which is the greatest advancement of all.
