On rare occasions the clerical vetting system fails and a Christian becomes a bishop or even a pope.
A Catholic Christian knows the gravity of sin and the necessity of repentance, which includes doing penance to expiate sin.
If Archbishop Gomez were a Christian, he would first privately and then publicly address Cardinal Mahony in terms such as these:
My dear brother, I fear for your salvation and I do not want to see you burn forever in the fires of hell, alienated from God, condemned by the voices of the abused children whose bodies and souls you allowed to be ruined.
You must immediately and publicly repent.
Send your cardinal’s hat back to the pope. Resign your priesthood. It is better to enter into life a layman than to be cast with a cardinal’s robes into Gehenna.
Become a lay bother at a poor monastery. Take the humblest jobs, cleaning the toilets and shoveling the stables. Spend every other moment on your knees until they are bloody, begging God to forgive you and not cast you into hell.
Tell the state that you will tell them everything and accept any punishment that they give you. Accept imprisonment and what you know probably awaits you in prison.
Perhaps the Lord will relent and will spare you. My dear brother, I pray that you repent before death, which comes to every man, and no one knows the day or hour.
So Gomez would speak if he were a Christian and not an ecclesiastical bureaucrat – something the Vatican does its best to prevent.
