I guess I was looking at this from the perspective of someone who either tries and can't come to an understanding of the Trinity OR someone who has not had the revelation of the Trinity. Personally, I'm Trinitarian through and through. But in a more extreme example, thinking of a tribal person in a remote region of the world who only has the revelation of Creation to acknowledge God. If he responds to this limited revelation with reverence for God, I believe he can have salvation, but this is all in the Wonderful Hands of the Lord.
To the person who struggles with it and can't comprehend it, I believe there can be Grace. Actually there can always be Grace. Who are we to say otherwise? The person who knows, can comprehend it and rejects it? In God's Hands. The Trinity is such a complicated notion to grasp, I guess I just have a problem with the belief that a concept that's not fully explainable even to a Trinitarian like myself, is outside of salvation looking in. I'm never one to say anyone is going to Hell, because I can't possibly understand the depths of the riches of the wisdom and the knowledge of God. How unsearchable are His ways. Oh, how I love the Doxology! :yes
