J. Castillo writes: "The center of Christianity is not God, but Jesus. I am referring to the earthly Jesus, born, lived and died in 1st century Palestine. That man, that human being, is the center of Christianity because in him God revealed himself, made himself known, communicated and gave himself to us. So that, in Jesus, God entered our immanence and united with the human condition. Which means that it is in the human, and only in the human, that we can encounter God and relate to God. What Christian theology affirms, when it speaks of the mystery of the incarnation of God in Jesus, represents, among other things, fundamentally, the event of the humanization of God, as it was realized and experienced in that human being who was Jesus of Nazareth".
