In the incarnation, two realities which were philosophically and theologically impossible to combine, have been demonstrably united in Christ. This union is impossible, but it is nonetheless accomplished as a simple act of God’s infinite power; the invisible Lord is now made visible, the Immaterial One is made flesh, he who cannot be limited accepts the limitations of an earthly life, the Immortal One comes willingly to his own death.

— McGuckin in St. Cyril, On the Unity of Christ, 35–6.
