One view of the church defines it as a group of Christians gathered out of the body of professing Christians, under the confessional flag of a fully developed orthodoxy. This was the view of J. Gresham Machen and those who seceded from mainline Presbyterianism to form the Orthodox Presbyterian Church. The Presbyterian Church in America followed a similar pattern.
