2016 Wesleyan Discipline: 12-13
12. At its first General Conference in 1844, the Connection had adopted an article of religion on “Sanctification,” becoming the first denomination to do so. But the doctrine and experience suffered neglect and decline among all branches of Methodism in the mid-nineteenth century. To renew them, God raised up a revival of holiness promoted through literature, evangelistic meetings, and camp meetings that swept throughout Methodism and across denominational lines. The first national camp meeting, which developed into the National Holiness Association, was held in 1867. The revival led to the establishment of several new holiness denominations and to the renewing and redirecting of others.
13. This spiritual revival, promoted vigorously by a corps of itinerant evangelists, soon established holiness as the major tenet of the Wesleyan Methodist Connection, which had formerly majored on social and political reform. In 1883, the General Conference adopted a resolution requiring the preaching of entire sanctification, and by 1893 new articles of religion on regeneration and entire sanctification had been adopted by the General Conference, the annual conferences, and local churches.
