Of Public Reading of the Holy Scriptures
This section of the directory states that reading belongs to the ministerial office. The Scottish Church had been used to readers for the earlier part of the service. By the 1640s they were mainly men who had the ministry in view. The directory permits such to occasionally read and preach, if allowed by the presbytery. This was a concession compared to the norm of Reformed churches, judged by practice in Europe, but more strict than the Independent view. The Independents were in favor of greater lay participation; indeed, the Scots were fearful that the liberty granted to expound would provide an opportunity for lay preaching.
The directory anticipates that the canonical books will be read in order so that "ordinarily, where the reading in either Testament endeth on one Lord's Day, it is to begin the next." The value of this, particularly given low levels of literacy, is obvious. More frequent (additional) reading of books like the book of Psalms is recommended. Any exposition is to follow the reading, not to be interspersed with it. This statement was not a direction to add expository comments, but was soon elaborated in Scotland to an extended lecture/commentary distinct from the subsequent sermon, a practice already common among the Independents in England. In effect the "double sermon" embodied two traditions -- the exposition of Scripture favored by the early Reformers and a doctrinal discourse on an isolated text more usual in the pre-Reformation context.[23] Indeed, strange as it may seem, reading of Scripture as a distinct element in worship was widely absent from Scottish services until the nineteenth century, being swallowed up by expository comments -- hence the direction of the Established Church of Scotland Assembly in 1856.[24]
[23] This is the hypothesis of Old, The Reading and Preaching of the Scriptures, 5:28-30.
[24] In 1856 ministers were enjoined "to observe the recommendations contained in it respecting the reading of the Scriptures of the Old and New Testaments at each diet of worship," and the hope is also expressed "that the principles maintained in that Directory will be duly observed."
