Apostle Paul disagrees with you mightily...
1 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, 2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. 3 For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He was raised on the third day according to the Scriptures,[1 Cor. 15]
God the Father and God the Spirit did not die. However, in the flesh, God the Son did die. Notice, I said in the FLESH He died. His Spirit went to the Father, but He died in the flesh.
