Apostolic means all the Apostles.
You really did not answer my question. Is it what you often have called dodging?
I don't know when the practice of drawing straws ceased, probably as the Infant Church matured. Just because it's biblical does not make it doctrinal, and the Church has the authority to change non-doctrinal practices. It's hardly practical for 300 bishops to draw straws.
Impractical? Drawing straws or lots is simply letting everyone know that the decision belongs to God alone. Whether it is only two or a thousand, what is impractical for God?
Jesus chose twelve but he had other disciples as we see when he sent out 70. The point of my question was why is the number twelve no longer significant as it was when Jesus chose that particular number of followers. It was no accident that he chose twelve any more than it was an accident that Jacob had twelve sons.They did, they are called bishops. Would you like some of their names?
