Well, the woman is a barking mad heretic, but this:
"But for us to assume that God could not act in other ways is, I think, to put God in an awfully small box."
Doesn't this single line, divorced from all the other heresy she spouted, make a very Orthodox statement?
The single line, yes. But she evinces a certitude about the possibility of salvation outside the visible bounds of the Church (even as she misconceives the Church), while we remain agnostic about the question.
Certainly no man comes to the Father, save through the Son, who is, indeed, the Way, the Life and the Truth. But whether there are non-standard ways by which this is accomplished for those deprived of the light of the Gospel is known only to God.
A person being saved may not *know* he is being saved through Christ and through Christ's Church, but that's what's happening all the same. He might be praying on the surface in the name of Vishnu or following Mohammed, but Vishnu or Mohammed won't be acting: Christ will.
