The Keys of the House of David

In matthew 18, such that all the apostles would also have their own set of keys. Whatever you loose on earth will be loosed in heaven. But if that explains the keys, then wouldn't that then that connection still exist? In first kings, two, three and four, is established as king. He establishes the cabinet a, the 12 royal ministers. The pope's over the years, the centuries, will invariably lead the church to an authoritative understanding of right doctrine. And so this is why vatican one, teaching papal primacy and infallibility, needs to be balanced with episcopal collegiality.
