Denying God’s will? A sin of the Holy Spirit that is unforgiveable either in the Confessional or by God.
Anytime we sin we deny God's will. His will is for us to not sin.
Therefore, based on catholic teaching, none of us can be forgiven for any sins we commit. That's some plan catholics have.
Good thing we have the Bible to show us otherwise for it teaches that ALL sins are forgiven.
Where did you get the idea that's "catholic teaching"?
