I don't follow what you're going on about now, at all.
But I doubt seriously that we're likely to come to great agreement on constructions of Scriptural reality on such points this side of Heaven.
Wish it were otherwise and perhaps God WILL make the unity differently than I think.
I think He will insist that it's based on Christ's Blood first, middle and last--and the Love and Grace, forebearance flowing out of that vs agreeing on every jot and tittle.
And, where reasonable people can differ both based on Scripture, as long as our hearts are intent on intimacy with God and our behavior earnestly leaning that way, I am confident God will make up the differences.
