"My God, my God, why hast thou forsaken me?" Is used by Charles Stanley to vindicate the separation of the Godhead. There are two options that alleviate the difficulty of destroying the Trinity. First, the word "forsake’" does not always mean to separate. In this case it means to "leave in the lurch," that is, to withhold the hand of protection in the hour of Christ’s greatest need. This is "forsaking" without separating. It means to refuse to rescue from this situation. For many reasons we must consider viable options that coincide with Scripture and bring honor to God without causing a division within the Godhead, thereby preserving the Oneness of The Triune God.

Another option is that the words of Christ were cries of humanity in which he "felt" abandoned, when in actuality he was not.

The words, "My God, my God, why hast thou forsaken me?" refer back to Psalm 22, which is a prophecy of the gruesome death that the Messiah was to suffer. The Psalm illuminates our first option by stating "why are thou so far from helping me?" The question resides in which way was God "far from helping Him," and "forsaking" him. The text of Psalm 22 reveals this a little more clearly. The abandonment that was experienced was not a separation in the Trinity because of the Father's displeasure, but an abandonment to suffering. In Psalm 22:1, it was the feeling of the righteous man that God is "far from helping him." To say that this is depicting an actual separation from God is out of harmony with subsequent verses that express the righteous man's confidence in God's presence and help. (verses 4, 9, 19.) 

In this Psalm which is doubtlessly a prophecy concerning the crucifixion, we are told the exact opposite of what Charles Stanley is teaching us. Concerning the cry of perceived abandonment that we read in Psalm 22:1, we must balance this in the light of what follows in its context in 22:24, "For he hath not despised nor abhorred the affliction of the afflicted; neither hath he hid his face from him; but when he cried unto him, he heard." Psalm 22:24

God the Father did not turn His back on Jesus, and there was no rift in the Trinity. God the Father and the Holy Spirit "forsook" the Son only in the sense that they did not rush in and rescue him during his immense agony and suffering. Also, take notice that nowhere in this detailed prophecy does it even imply that the atonement was a punishment or payment for sin.
