So NOW you got, instead of just PRESBYTERIANism being UNTRUE; you'vre got ALL of them being 'untrue'.
Once again:WHAT WAS UNTRUE about them??
They weren’t the church as it was established by Christ. That doesn’t mean that they didn’t retain some true doctrines. But they no longer had the priesthood authority, they didn’t have the characteristics of the church founded by Christ, even to the extent those characteristics are set forth in the Bible. Some doctrine had been corrupted.
