Some here forget that it’s written clearly...’Our righteousness’ is as filthy rags before God....so when some believe one sin won’t matter, they should consider if our “righteousness” is as filthy rags...imagine what ONE SIN is before God.
And Catholics seem to not realize that Christ took our sins upon Himself. Our sins have been forgiven and removed as far as East is from West. Claiming that we need to “pay for our sins in purgatory” is denying Christ.
