Christ founded the Catholic church. It started as the hierarchy it has been ever since.
At the Summit, eternal and divine is Almighty God. Father, Son and Holy Spirit; Every authority and power is from HIM, directed downward.
Peter the Vicar of Christ; his successors; then down to the shepherds; his bishops and priests. Then the laity. With or WITHOUT the Bible; which is a comfort; not a rule of faith in itself.
