Probably need to open a different thread for this, but
@Pacman and I have really been retooling our thoughts on this lately.
If Scripture is based on patriarchy and the elders were the wisest patriarchs who sat in the gates, what happens when a splinter group get put out of families or synagogues for following Yeshua? Suddenly they have no patriarchal access or covering. Suppose, Paul was offering a 'temporary' instruction to the new fellowships on what to do until established patriarchs grew up in the community to fill the elder role? Maybe he never intended it to become an 'office' that people rotated through. It was a normal duty in the families and clans of Israel, but he needed a placeholder that the best could be put in and his expectation was that once the fellowships matured and the communities came along, the patriarchs would rise and resume their rightful place, ala 1 Cor. 11:3!!
Thoughts?
