CANON XX.-If any one saith, that the man who is justified and how perfect soever, is not bound to observe the commandments of God and of the Church, but only to believe; as if indeed the Gospel were a bare and absolute promise of eternal life, without the condition of observing the commandments ; let him be anathema.Troubles you?
Salvation is by grace through faith in Christ, not of works so that no man may boast.
We are not bound to works to earn salvation, and any works we do is in obedience to God, not the RCC, who has no authority over the believer.
