Maximus the Confessor on the Incarnation

… On the incarnation being part of God’s divine plan from all eternity, irrespective of humanity’s primal disobedience.

“He who, by the sheer inclination of his will, established the beginning of all creation, seen and unseen, before all the ages and before that beginning of created beings, had an ineffably good plan for those creatures. The plan [even before the sin and fall] was for him to mingle, without change on his part, with the human nature by true hypostatic union, to unite human nature to himself while remaining immutable, so that he might become a man, as he alone knew how, and so that he might deify humanity in union with himself. Also, according to this plan, it is clear that God wisely divided “the ages” between those intended for God to become human, and those intended for humanity to become divine” (Maximus the Confessor, Ad Thalassium 22, as quoted in Harink’s commentary on 1 Peter, pg 40).
