Under Bergoglio's leadership, Argentina's bishops issued a collective apology in October 2012 for the church's failures to protect its flock. But the statement blamed the era's violence in roughly equal measure on both the junta and its enemies.
"Bergoglio has been very critical of human rights violations during the dictatorship, but he has always also criticized the leftist guerrillas; he doesn't forget that side," Rubin said.
The bishops also said "we exhort those who have information about the location of stolen babies, or who know where bodies were secretly buried, that they realize they are morally obligated to inform the pertinent authorities."
That statement came far too late for some activists, who accused Bergoglio of being more concerned about the church's image than about aiding the many human rights investigations of the Kirchners' era.
Bergoglio twice invoked his right under Argentine law to refuse to appear in open court, and when he eventually did testify in 2010, his answers were evasive, human rights attorney Myriam Bregman said.
At least two cases directly involved Bergoglio. One examined the torture of two of his Jesuit priests — Orlando Yorio and Francisco Jalics — who were kidnapped in 1976 from the slums where they advocated liberation theology.
Yorio accused Bergoglio of effectively handing them over to the death squads by declining to tell the regime that he endorsed their work. Jalics refused to discuss it after moving into seclusion in a German monastery.
Both men were freed after Bergoglio took extraordinary, behind-the-scenes action to save them — including persuading dictator Jorge Videla's family priest to call in sick so that he could say Mass in the junta leader's home, where he privately appealed for mercy. His intervention likely saved their lives, but Bergoglio never shared the details until Rubin interviewed him for the 2010 biography.
