The Vatican issued a statement Saturday saying it was aware that such an investigation may produce evidence “that choices were taken that would not be consonant with a contemporary approach to such issues.”

However, it said the Vatican would “follow the path of truth wherever it may lead.”

The statement did not address allegations that Francis himself knew of sexual misconduct allegations against now ex-Cardinal Theodore McCarrick in 2013 and rehabilitated him anyway.

McCarrick’s title was tripped away in July. He was accused three times of sexual misconduct with adults over the years.

He has also been accused of abusing a minor. That case is awaiting a church trial.

The Vatican knew as early as 2000 that seminarians reported McCarrick pressured them to sleep with him.
