Sinner saved by grace not works here. (Southern Baptist)
No indulgence necessary.
Just the blood of a truly awesome God.
Jesus said on the cross “It is finished”.
The final sacrifice was and is complete. It is by His work that we are saved. Sola Gracia.
Anything else puts us back in slavery to the old law. Paul wrote extensively on that.
Indulgences are only of value to the saved.
