There are no unforgivable sins. CCC 982 - "There is no one, however wicked and guilty, who may not confidently hope for forgiveness, provided his repentance is honest. Christ who died for all men desires that in his Church the gates of forgiveness should always be open to anyone who turns away from sin. Reconciliation through the sacrament of Penance can be granted only to those who have repented for having violated the sign of the covenant and of fidelity to Christ, and who are committed to living in complete continence.
Might want to read the 'fine' print, as there IS an unforgivable sin, although adultery or marriage or administrative policy are NOT that particular sin. And there is NO administrative policy that will set aside that penalty....
Jesus said there was an unforgivable sin... do you know what it is?
