You have NOT read and UNDERSTOOD Romans 4. “Righteous at the time of their death”? The chapter explains how one is GIVEN the righteousness of God through faith in Christ...NOW. There is no lack needing to be cleansed in “purgatory”. You have the righteousness of Christ CREDITED to you through faith. Why won’t you accept this?
Romans 4 speaks of me also? Where is that written? Romans 4 speaks of the fact that Abraham was justified before he was circumcised, “Not in circumcision, but in uncircumcision”, “justified by faith, without the works of the law” (Romans 3:28).
These passages have nothing to do with the existence of Purgatory.
