An interesting line of divergence from the current teachings of the Friends was led, toward the end of the seventeenth century, by George Keith, for thirty years a recognized preacher of the Society. One is impressed, in a superficial glance at the story, with the reasonableness and wisdom of some of Keith's positions, and with the intellectual vigor of the man. But the discussion grew into an acrimonious controversy, and the controversy deepened into a schism, which culminated in the disowning of Keith by the Friends in America, and afterward by the London Yearly Meeting, to which he had appealed. Dropped thus by his old friends, he was taken up by the English Episcopalians and ordained by the Bishop of London, and in 1702 returned to America as the first missionary of the newly organized Society for the Propagation of the Gospel in Foreign Parts. An active missionary campaign was begun and sustained by the large resources of the Venerable Society until the outbreak of the War of Independence. The movement had great advantages for success. It was next of kin to the expiring Swedish Lutheran Church in the three counties that became afterward the State of Delaware, and heir to its venerable edifices and its good will; it was the official and court church of the royal governors, and after the degenerate sons of William Penn abandoned the simple worship, as well as the clean living, in which their father delighted, it was the church promoted by the proprietary interest; withal it proved itself, both then and afterward, to hold a deposit of truth and of usages of worship peculiarly adapted to supplement the defects of the Quaker system. It is not easy to explain the ill success of the enterprise. In Philadelphia it took strong root, and the building, in 1727, of Christ Church, which survives to this day, a monument of architectural beauty as well as historical interest, marks an important epoch in the progress of Christianity in America. But in the rural districts the work languished. Parishes, seemingly well equipped, fell into a "deplorable condition"; churches were closed and parishes dwindled away. About the year 1724 Governor Keith reported to the Bishop of London that outside the city there were "twelve or thirteen little edifices, at times supplied by one or other of the poor missionaries sent from the society." Nearly all that had been gained by the Episcopal Church in Pennsylvania, where the "Venerable Society" had maintained at times forty-seven missionaries and twenty-four central stations, was wiped out by the Revolutionary War.[120:1]
