The Apostles appointed successors. They are the men chosen to have the fullness of the Priesthood of Jesus Christ. They exist in an unbroken line through today. The Apostolic succession is the heart of Our Lord’s promise to us that the Church would prevail.
You appear to deny that the Apostles had the authority to appoint successors. Is that what you believe?
I don't doubt what you believe, but could you show us in the scriptures where anyone had the power to appoint successors?
