As the main object for which the Solemn League and Covenant was framed, was to secure the utmost practicable degree of uniformity in the religious worship of both countries; and, as the English Divines had already met at Westminster to take the whole subject into consideration, and had requested the assistance of Commissioners from the Church of Scotland, the General Assembly named some of the most eminent of their ministers and elders as Commissioners to the Westminster Assembly. These were, Alexander Henderson, Robert Douglas, Robert Baillie, Samuel Rutherford, and George Gillespie, ministers; and the Earl of Cassilis, Lord Maitland, and Sir Archibald Johnston of Warriston, elders; but neither the Earl of Cassilis nor Robert Douglas went. Three of these, Lord Maitland, Henderson, and Gillespie, set off for London, along with the English Commissioners, immediately after the rising of the General Assembly; the other three, Warriston, Rutherford, and Baillie, followed about a month afterwards. On the 15th of September the Scottish Commissioners were received into the Westminster Assembly with great kindness and courtesy; and, on the 25th of the same month, the Solemn League and Covenant was publicly sworn and subscribed by both Parliament and Assembly, after addresses by Nyo and Henderson. It was not, however, till the 12th of October, that the Westminster Assembly commenced its serious deliberations concerning Church Government, Discipline, and a Directory of Worship, in the hope of arriving at such conclusions as might produce religious uniformity in the Churches of England, Scotland, and Ireland, if not also with the Reformed Churches of the Continent.
