Unity of Christ and the Father while on the Cross

Dr. Couch, it seems the unity or immutability of God is destroyed by the so-called separation of Christ from the Father when He was on the cross. Most Bible teachers seem to just give the usual standard answer and do not work the biblical text on giving the right answer. I know you work the languages, so I'm asking you what the passage (Matt. 27:46) is really saying from the Hebrew and Greek languages. What do you think? ANSWER:  The passage reads, "My God, My God, why have You forsaken Me?" Christ is quoting Psalm 22:1. The Hebrew word for "forsaken" in Psalm 22:1 is A'Zav with the meaning of "to abandon, to take away one's favor," with the idea: "To come up to someone, see a need, and walk away from that need." In Greek the word "forsake" is egkataleipo. It is in an Aorist form and carries the idea "to desert," to "leave one in straits, to leave one helpless, to leave one behind."    The persons in the Trinity did not cut ties when Christ died, and took upon Himself our sins, but the heavenly Father left the Son to face the pain of crucifixion, left Him in the circumstances of the death He was facing. The Father and Son were not breaking their Trinity relationship. They, along with the Holy Spirit, remained as joined as the three persons in the Godhead: Father, Son, and Spirit. They have an eternal relationship that cannot be broken.    The incarnation of Christ is a mystery and it is difficult to understand what happened in Christ's death on the cross. It cannot be said that God died, so His death is indeed difficult to explain! Some argue that only the physical of the Lord actually died. And even with that, we know that Christ did not undergo decay in His body. This is made clear from Psalm 22:10: "Neither will You allow Your Holy One to undergo decay." As deity the Lord did not "disappear." For He said prophetically "My flesh also will dwell securely. For You will not abandon My soul to Sheol [to the grave]" (vv. 9b-10a).    Psalm 22:11 seems to say that Christ, in His death, remained conscience just as we will when we pass. "In Your presence is fullness of joy; in Your right hand there are pleasures forever." In other words, the Lord remained in His relationship, with joy and comfort, with the heavenly Father when He physically died! A lot of this is a mystery but what I've written seems to make sense biblically.    Thanks for asking.    Dr. Mal Couch
