According to Paul, that means, according to scripture, their created nature has everything to do with why women are not ordained as elders.

"For Adam was first formed, then Eve. And Adam was not deceived, but the woman being deceived was in the transgression. Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety."

These verses are the reason Paul gives for not allowing women to have authority over a man.  Paul reasons essentially that the woman was made for man, to be his help mate. That her primary function as help mate is to help him begat children.

John Calvin wasn't even a twinkle in his daddy's eye when Paul wrote this.  Let's stick to the original sources. "Calvinism" doesn't not belong in our conversation.
