Accusations that Pope Francis denounced two priests to Argentina's military junta during the 1970s have been denied by one of the survivors in a boost to the reputation of the new pontiff.

Francisco Jalics, who now lives in a German monastery, issued an online statement on Wednesday to clear up what he said were misinterpretations of his earlier comments about the role played by the pope in his five-month incarceration by the navy.

He said he was addressing reports that he and another Jesuit priest, Orlando Yorio, were imprisoned because the leader of their order, Jorge Bergoglio – as the pope was known until last week – passed on information about them to the authorities.

"I myself was once inclined to believe that we were the victims of a denunciation," Jalics said. "[But] at the end of the 90s, after numerous conversations, it became clear to me that this suspicion was unfounded. It is therefore wrong to assert that our capture took place at the initiative of Father Bergoglio."

The latest comments follow a less categorical statement that he made last week soon after the pope was chosen. In that earlier comment, he said he and Bergoglio had reconciled and "hugged solemnly" in 2000. But he also noted that he "could not comment on the role played by Father Bergoglio in these events".

Argentinian critics of the pope have continued to accuse him of wrongdoing, based on documents and old testimonies of Yorio, who died several years ago. Jalics' failure to deny this added to their suspicions.

But in the latest statement, Jalics said "Some commentaries imply the opposite of what I meant."

By contrast, his words on Wednesday were unequivocal: "The fact is: Orlando Yorio and I were not denounced by Father Bergoglio."

His comments are likely to quash many doubts, but in Argentina they are unlikely to go away completely given the frustration felt by some victims, leftist priests and government figures that Bergoglio has not adequately addressed the close links that the church had with the dictatorship.

While many accept that it was dangerous to openly confront the military during that murderous era, others feel that church leaders should subsequently have condemned the wrongdoing by priests who were so closely involved in torture and incarceration of political enemies that they have subsequently been jailed.

Bergoglio has never been accused of a crime. Vatican spokesman Federico Lombardi noted on Friday that on the contrary "there have been many declarations demonstrating how much Bergoglio did to protect many persons at the time".
