Entering into continental Europe, the Quaker Reformation found itself anticipated in the progress of religious history. The protests of the Anabaptists against what they deemed the shortcomings of the Lutheran Reformation had been attended with far wilder extravagances than those of the early Quakers, and had been repressed with ruthless severity. But the political and militant Anabaptists were succeeded by communities of mild and inoffensive non-resistants, governing themselves by a narrow and rigorous discipline, and differing from the order of Quakers mainly at this point, that whereas the Quakers rejected all sacraments, these insisted strenuously on their own views of Baptism and the Supper, and added to them the ordinance of the Washing of Feet. These communities were to be found throughout Protestant Europe, from the Alps to the North Sea, but were best known in Holland and Lower Germany, where they were called Mennonites, from the priest, Menno Simons, who, a hundred years before George Fox, had enunciated the same principles of duty founded on the strict interpretation of the Sermon on the Mount. The combination of circumstances to promote the "Holy Experiment" of William Penn is something prodigious. How he could be a petted favorite at the shameful court of the last two Stuarts, while his brethren throughout the realm were languishing under persecution, is a fact not in itself honorable, but capable of being honorably explained; and both the persecution and the court favor helped on his enterprise. The time was opportune; the period of tragical uncertainty in colonization was past; emigration had come to be a richly promising enterprise. For leader of the enterprise what endowment was lacking in the elegantly accomplished young courtier, holding as his own the richest domain that could be carved out of a continent, who was at the same time brother, in unaffected humility and unbounded generosity, in a great fraternity bound together by principles of ascetic self-denial and devotion to the kingdom of God?
