Again: I have no problem with acknowledging that in the early days of Adventism, positions on the Trinity were held that were not orthodox. I would not argue against the idea that some elements of those non-orthodox positions may exist in some SDA members today.
I think that both Gustave and I agree that the full nature of the Godhead is well beyond our human experience and understanding. But, some aspects of that have been revealed to us in Scripture and therefore are worthy of discussion.
I hope that we can have some enlightenment from the person who will be working with us/me.
