The sexual abuse scandal that festered under [Pope John Paul's] watch remains a stain on his legacy. Pope Francis has inherited John Paul's most notorious failure on the sex abuse front - the Legion of Christ order, which John Paul and his top advisers held up as a model. The Legion admitted that its late founder sexually abused his seminarians and fathered three children. Yet the Legion's 2009 admission about the Rev. Marcial Maciel's double life was by no means news to the Vatican. Documents from the archives of the Vatican's then-Sacred Congregation for Religious show how a succession of papacies ... simply turned a blind eye to credible reports that Maciel was a con artist, drug addict, pedophile and religious fraud. The documents show the Holy See was well aware of Maciel's drug abuse, sexual abuse and financial improprieties as early as 1956, when it ordered an initial investigation and suspended him for two years to kick a morphine habit. Maciel's fraud, one of the greatest scandals of the 20th-century Catholic Church, raises uncomfortable questions for today's Vatican about how so many people could have been duped for so long. [This] brings into question how the church's own structure, values and priorities enabled a cult-like order to grow from within and how far accountability for all the harm done should go. It begs the question of whether the order has really been purged of the abuses that allowed generations of priests to subject themselves to blind obedience to a false prophet.
