In the same way Christ and the Father are one for Christ was in the bosom of the Father. But when he came to earth we saw him as a human being, so we knew that there is the Father and the Son, and we were able to distinguish between the two of them, but in reality and from the first place, they are one. That is why we say about him “the Lord Jesus” , because the son of God is God, as we say to you, “You are the son of this”, so if your father was a king, you will also be called a king, because you are the son of a king and you share with your father the rule and the kingship. Likewise, the Son of God shares the deity with his Father, so we say Christ is God.

The Holy Spirit comes to anyone who works for the kingdom (of heaven). The Holy Spirit works in anyone, but He only dwells in Christians and precisely after the baptism, because Christ is the one who sends the Holy Spirit to dwell in those who only believe in him.
