In the chapter "_Of human Church Regulations_," the pastors are exhorted to insist upon the principal matters in their sermons. Sundays and festival-days are to be observed. Yea, they even suffer Apostles' and Saints' days to remain. But on the latter they are to permit labor.

Matters relating to marriage are also briefly considered. Of _free will_ it says, that we are able to perform worldly piety and good works by our own strength, given us and preserved for this purpose by God. This is the righteousness of the flesh. But they also teach--"Man by his own power cannot purify his heart, and produce divine gifts, such as true repentance from sin, a true and unfeigned fear of God, true faith, cordial love, chastity, an absence of revenge, true patience, earnest prayer, freedom from covetousness, &c." _Concerning Christian Liberty_, the errors of the vulgar are set aside, and liberty in Christ exhibited.

Overseers, called Superintendents, selected from the pastors, were appointed in particular districts. Besides this, this instruction of the visitation devotes a full chapter to schools.
