On the Administration of the Lord's Table, Kirk of Scotland (1560)

In 1560, the kirk sent forth its creedal testimony in the Scottish Confession, which was written by six ministers: John Knox, John Douglas, John Row, John Spottiswoode, John Willock, and John Winram. These ministers were also commissioned to draft "in a volume the policy and discipline of the kirk." The latter became the First Book of Discipline of the Scottish Church.

From the First Book of Discipline (1560) of the Kirk of Scotland, giving directions for the administration fo the Lord’s Supper (The Ninth Head); note their advice regarding frequency:

Four times in the year we think sufficient to the administration of the Lord's Table, which we desire to be distinct, that the superstition of times may be avoided so far as may be. Your honours are not ignorant how superstitiously the people run to that action at Pasche, even as [if] the time gave virtue to the sacrament; and how the rest of the whole year they are careless and negligent, as that it appertains not unto them but at that time only. We think therefore most expedient, that the first Sunday of March be appointed for one [time]; the first Sunday of June for another; the first Sunday of September for the third; and the first Sunday of December for the fourth. We do not deny but that any several church, for reasonable causes, may change the time, and may minister ofter; but we study to suppress superstition. All ministers must be admonished to be more careful to instruct the ignorant than ready to satisfy their appetites; and more sharp in examination than indulgent, in admitting to that great mystery such as are ignorant of the use and virtue of the same. And therefore we think that the administration of the Table ought never to be without that examination pass before, especially of those whose knowledge is suspect. We think that none are apt to be admitted to that mystery who cannot formally say the Lord's Prayer, the articles of the belief, and declare the sum of the law.
