McGuckin notes that the vagueness of the Sacra resulted in wide variations of interpretation by different bishops. In particular, the vastness of John of Antioch's ecclesiastical territory required a lengthy period to notify and gather his delegates. Because the overland trip from Antioch to Ephesus was long and arduous, John composed his delegation of his metropolitan bishops who were restricted to bring no more than two suffragans each. By doing so, he minimized the number who would have to travel to Ephesus.
