Well, you need to tell the priest on the forum that cause HE'S the one who said that, not me.

"But God DID die on the cross! That's precisely why it MATTERS that Jesus died on the cross!"
Yeah, I saw that post. I choose not to get involved in that conversation.
I do not believe that God died on the cross in the sense that He ceased to exist.
But I think the question can be raised whether God tasted death. That is, are the three persons of the Trinity so closely united one to another, that when Jesus experienced the condition of death, i.e., the separation of His body from His soul, did the Father and the Holy Spirit fully share in that experience? Or, because the Father and Holy Spirit are not in the flesh, is it only the incarnate Jesus that experienced this condition?
