"September 6, 2017 (LifeSiteNews) -- Cardinal Carlo Caffarra, one of the four cardinals who sent Pope Francis the dubia asking for clarity on Amoris Laetitia, died at 79, the Vatican confirmed.
He is the second dubia cardinal to die in the last two months. German Cardinal Joachim Meisner died peacefully in his sleep in July, holding his breviary and preparing to offer Mass.
The two remaining dubia signers are Cardinals Raymond Burke, 69, and Walter Brandmuller, 88.
Cardinal Caffarra, former archbishop of Bologna, was tasked by Saint Pope John Paul II more than three decades ago with founding an institute to study marriage and the family. He has been a respected leader in reinvigorating the life and family movement within the Church.
Along with a doctorate in canon law, he was a specialist in moral theology. In his early priesthood he was a professor of moral theology to seminarians, giving special attention to the Church's doctrine on marriage and the ethics of procreation. He later taught medical ethics in Rome.
He was nominated an expert at the Synod of Bishops on Matrimony and the Family in 1980, and the following year, was appointed by John Paul II to as founder and president of the John Paul II Pontifical Institute for Studies on Marriage and the Family. From 1983-88 he held the position of Consultor of the Congregation for the Doctrine of the Faith.
The cardinal served as a member of the Congregation for the Causes of Saints, the Supreme Tribunal of the Apostolic Signatura, the Pontifical Council for the Family, and the Pontifical Academy for Life.
In 2008, Caffarra gave an interview in which he spoke about a letter he had received from the last Fatima seer, Sister Lucia dos Santos, concerning the final battle between God and Satan. When the cardinal wrote to Sister Lucia 36 years ago asking for her prayers as he began the process of founding the institute, he never expected a reply. Instead, the seer responded with a message of profound significance.
In [her letter] we find written: ‘The final battle between the Lord and the reign of Satan will be about marriage and the family. Don’t be afraid,’ she added, ‘because anyone who operates for the sanctity of marriage and the family will always be contended and opposed in every way, because this is the decisive issue.’ And then she concluded: ‘However, Our Lady has already crushed its head.’"
