This is just BS and a denial of the necessity of baptism and of the Chruch. It sounds like some new-age, Protestant fairy tale where all the “good” people that died outside the Chruch will get a pass and have the same reward as Catholics.
If you want to argue that those in limbo eventually go to the New Earth, then that’s plausible. But they would NOT enter the new heaven. Nor would their original sin be remitted somehow. That’s heresy.
For the 53rd time, you comparing Moses to an invincibly ignorant native is blasphemy. Moses followed the Old Law; the native Indian followed the natural law, only. Moses was circuмcised. Moses believed in the redeemer. The ONLY THING Moses lacked was baptism, which he received in Limbo. The native Indian believed in no God, or one that was general. He had no religion. He worshipped God in no significant religious way. The 2 are INCOMPARABLE.
