"That a uniform order of Liturgy or divine service be set down to be read in all Kirks on the ordinary days of prayer and every Sabbath day before the sermon, to the end the common people may be acquainted therewith, and by custom may learn to serve God rightly. And to this intent the Assembly has appointed ... to revise the Book of Common Prayer contained in the Psalm Book, and to set down a common form of ordinary service to be used in all times hereafter." The work thus authorized of revising the Book of Common Order was at once undertaken by those appointed thereto, but although a draft was made and much labor was expended upon it during a term of several years, the book in its revised form was never introduced into the Scottish Church. By the time it had received its final revision at the hands of the King and his Scotch advisors in London, such events had transpired, and such a spirit of opposition had been aroused in Scotland by other measures, that it was deemed wise to withhold it, and the death of James occurring in 1625, while it was still unpublished, the book in its revised form was retained by Spottiswoode, Bishop of St. Andrew's, and appears to have been forgotten for years, even by its most active promoters. From correspondence in the time of Charles First, however, it appears that James had not relinquished his aim of imposing the new book upon the Scottish Church, and it is probable that his death alone prevented the attempt being made to carry out his cherished purpose. Much of the voluminous correspondence, which at this time passed between James and the leaders of the Scottish Church, is still extant and it serves to indicate some of the anticipated changes in the forms of worship. In the regular worship appointed for the Lord's Day there was to be introduced a liturgy which was to be used before the sermon; the Ten Commandments were to be read, and after each of them the people were to be instructed to respond, or, as the rubric directed: "After every Commandment they ask mercy of God for their transgression of the same in this manner,--Lord have mercy upon us and incline our hearts to keep this law."
