Since you do not believe we are counted righteous APART from works, now, Today, forever—CCC forbid!—you NEED Rome’s inventions to make up for the perceived shortfall (see: Pope’s blog post at source). Rome’s Purgatory is a compounded error resulting from NOT BELIEVING ROMANS 4, and it slanders the Promise given to Abraham and suggests the imputed righteousness of God by faith in Christ is not the all-sufficient answer He proclaims it to be in...ROMANS 4.
What I believe and need you can only guess; for your information, I fully believe everything in the Holy Scripture because I am Catholic. The question remains: what does Abraham faith and righteousness have to do with the existence of Purgatory?
