We read in Mark 15: 42-44:
"When evening had come, and since it was the day of Preparation, that is, the day before the sabbath, Joseph of Arimathea, a respected member of the council, who was also himself waiting expectantly for the kingdom of God, went boldly to Pilate and asked for the body of Jesus. Then Pilate wondered if he were already dead; and summoning the centurion, he asked him whether he had been dead for some time. "
That implies that Jesus'death on the cross happened earlier than had been expected. Some medical professionals theorize that Jesus died of a heart failure, to which extreme mental stress had significantly contributed. They believe that the Lord's psychological trauma did not end with the Sweating of Blood at Gethsemane, rather followed Him to the Cross.
Now, one should not expect that the Creed will be re-written to state that Jesus died on the Cross, of heart-failure. But, understanding the theory helps one to look at the mental agony of Jesus with the same gravity as his physical suffering.
My question therefore, is: Has the Catholic Church taken cognizance of the theory that the terminal cause of Jesus's death on the cross was heart-failure ?
