"Based on the arguments you and I had about the scripture, I'd say this task of yours is not merely hard but outright impossible"
It is for natural man, that's why the Holy Spirit was sent to teach us and to open the scriptures to all the children of God who want to know. You don't have to twist the plain definition of simple words and phrases like grace, wife, brother, perfect, private interpretation to suit church dogma or rely on dogma of the church to interpret the scripture. By the Holy Spirit, the scriptures are perspicuous to all who come to them humbly to be taught and changed into the likeness of the risen Christ.
I discussed scripture with you and others many times and I am left with the firm impression that the scripture is largely a closed book to you, sorry. I also think that it is an uncommon arrogance to think that the Holy Spirit has guided your study of the scripture in a way that the Church of two thousand years has completely missed.
