John Paul died on Saturday, on the eve of the Divine Mercy Holiday, 2 April 2005. The official time of death on his death certificate was 9:37 pm, but a few sources reported 9:33 pm. The death certificate stated that when the Pope died, he had Parkinson's disease, with serious breathing difficulties. The Pope had tracheotomy surgery in mid February but it did not help and he lost weight. He also had an enlarged prostate, urinary infection and other problems. The cause of death were that his kidneys failed, causing blood poisoning and infection brought by septic shock. John Paul II spoke his final words, “pozwólcie mi odejść do domu Ojca”, (“Let me depart to the house of the Father”), to his aides, and fell into a coma about four hours later.
