The comments are significant in lieu of revelations from Gaenswein’s book that the current pope and his retired predecessor had a differing of opinions more than once.

"I hope Pope Francis trusts me, I hope I haven't given him reason not to trust me anymore," the German prelate told journalist Bruno Vespa in a recorded interview.

Questioned about his future, Gaenswein said "the Holy Father will let me know in the coming days".

"I am faithful and loyal [to the pope] in the same way that I have been faithful to all his predecessors."

The memoir Nothing but the Truth: My Life Beside Benedict XVI, released shortly after the emeritus pope's funeral in January, did not intend to create "wars" within the Church, Gaenswein told Vespa.

"My only goal was to provide clarity even on points where there were many problems,” he said.

“Clarity means telling and providing the truth for all who wanted to know.

“No wars, no factions, I just wanted to give my testimony of the real things that happened.”

In his book, Gaenswein suggested there was friction between Benedict and Francis after the former resigned as the head of the Catholic Church in 2013.

According to the book, these differences regarded Francis' decision to reimpose restrictions on the traditional Latin Mass (reversing a decision made by his predecessor) as well as his softer line on homosexuality.

Pope Francis has denied there was any tension.

“There weren’t problems,” Francis said during an inflight press conference.

“On the contrary [to the rumours], I consulted Benedict for some decisions to be made, and he agreed. He agreed.”

“… he wasn’t embittered.”
