The Vatican has downplayed a 1997 letter to Irish bishops about handling cases of clerical sex abuse, saying the letter did not tell bishops to keep the cases secret from the police.

Jesuit Fr Federico Lombardi, the Vatican spokesman, said the letter aimed at ensuring the bishops fully followed Church law for dealing with accusations in order to avoid a situation in which an abusive priest could return to ministry on the technicality of his bishop mishandling the process.

The letter, brought to public attention this week by Ireland's RTE television and published by the Associated Press, was written by Archbishop Luciano Storero, then-nuncio to Ireland. The letter summarised the concerns of the Congregation for Clergy regarding proposed Irish norms for dealing with the sex abuse crisis.
