Yep. Opinion. Still dead. No Scripture.
Here is a scripture that I know that you posted or referenced, and it does give the basics
Galatians 3:
[26] For ye are all the children of God by faith in Christ Jesus.There are precursors to this in the OT, but I have too much work to do to chase them out presently.
[27] For as many of you as have been baptized into Christ have put on Christ.
[28] There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
[29] And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
