The Apostles were the hierarchy. There was no usurpation. Presbyters and deacons are Biblical too. It is telling that you believe God’s Church is essentially an usurpation.
“Of course we have the Mormons, Muslims, and Catholics who all claim to have “additional revelation” or authority trying to lead the only true “church”.”
So Muslims have a “church” now? The knots anti-Catholics tie themselves into are amazing. Also, Joseph Smith founded the Mormons. Muhammad founded Islam. Christ founded the Catholic Church.
“I’ve stayed with God’s written word and “search the scriptures daily, whether those things were so”.”
No, you merely rely on your interpretations.
No, Christ founded the catholic (small c) as in universal church of believers. The RCC confiscated the original pure intent and polluted it. Not much different then the Mormons or Muslims. BTW, the Muslims used the Old Testament and Mary is the only woman of note.
