Outside of the Catholic Church or Orthodox Churches who maintain apostolic succession, any salvation granted by the grace of God is not because of but despite this distance. If one has been given the information and opportunity to seek the grace from His Church and denies it is certainly in danger of the judgement.

This isn't to say that God wouldn't grant salvation to those with perfect contrition but who haven't been given the information and opportunity to join His Church, it would be presumptive to say otherwise.

The point is by intentionally distancing oneself from His Church built upon Pope Peter with each subsequent priest deriving apostolic authority from from the previous, you are playing with fire. Hell fire.
