A Catholic priest has offended parents at a Malvern East school by comparing paedophile priests to adulterous women in a school newsletter.

St Mary's Primary School parish priest Father Bill Edebohls also took aim at lawyers and the media for not showing enough mercy during the Royal Commission into Institutional Responses to Child Sex Abuse.

He said he was concerned the Royal Commission would not give victims an opportunity to heal.

"Why? Because both the media and the lawyers, like the baying crowd of men in the gospel ready to throw stones, don't understand the need for a justice that is drenched in mercy."
