This is rather a confusing piece. It is not tightly written. It leaves ambiguous the fate of one who is aware of the teachings of Christ, but simply rejects his divinity, and chooses not be baptized. If this person leads a moral life, is the Catholic doctrine that we still don't know that person's fate, or that we don't know of any way such person can get to heaven, but then just because we don't know, doesn't mean there isn't a way, or as McGowan of FR said, that as long as one doesn't believe the Catholic of Christian doctrine is true, but leads a moral life, then there is not impediment to heaven.
Confusion seems to reign, for whatever reason.
and God is not the author of confusion is he...
