You can pray for them all you want....but their eternal destination is determined when they die.
If believers in Christ...Heaven. If not...hell.
If the RCC position were valid all we have to do is pray all the dead into Heaven without benefit of knowing Christ.
That's not a NT position.
Heaven, and then raised into eternal life.
Hell, and raised into eternal death.

Sorry, just something I’m passionate about. ^^;
