The Book of Discipline had recognized the need for officials who would oversee local churches, supervise the establishment of new ones, and ensure that only qualified persons would serve as ministers. It specified that such officials, called superintendents, would be in charge of areas whose boundaries were intended to reflect the geographical configurations of the country. In the early 1560s five superintendents and three bishops who conformed to the new religious settlement had begun their work.

What this means is that there were five superintendents, of the Reformed persuasion, and three continuing bishops retaining their positions from the pre-Reformation polity. All were now united under the Church of Scotland and the Magistrate.
