[quote:1t02d2hq]O.k but when Jesus was dieing on the cross and said “My God, My God, why have you forsaken Me” was he talking to himself? if he was Jesus and God at that moment why would he say this.[/quote:1t02d2hq]
Here is just one example of how the early christians understood it.
[color=blue:1t02d2hq][i:1t02d2hq]”But the Son of God is the Logos of the Father, in idea and in operation; for after the pattern of Him and by Him were all things made, the Father and the Son being one. And, the Son being in the Father and the Father in the Son, in oneness and power of spirit, the understanding and reason of the Father is the Son of God. But if, in your surpassing intelligence, it occurs to you to inquire what is meant by the Son, I will state briefly that He is the first product of the Father, not as having been brought into existence (for from the beginning, God, who is the eternal mind, had the Logos in Himself, being from eternity instinct with Logos.” Athenagoras, Plea for Christians, 10 (A.D. 177).

The Trinity is not something that we are expected to understand in it’s totality. From our standpoint, He does indeed seem to be talking to Himself.
Hope that helps.
