As an addendum to my previous post comes the news that one of the Council Fathers still alive today is, in fact, not. Ten Days ago, on June 15, Archbishop Albert Joseph Tsiahoana passed away at the age of 84. At the time of Vaticanum II he was an auxiliary bishop of Diégo-Suarez in Madagascar. He would later become the archbishop of that same archdiocese, which today is called Antsiranana.
We are all mortals, and when considering the average age of the surviving Council Fathers it would be surprising if not more would enter eternal life before the Year of Faith opens.
