a stable Christian," which Barclay ascribed to a William Mitchell, a neighbouring catechist with whom Patrick Livingstone had had some disputation. Upon him therefore Robert Barclay fell with all the energy of honest indignation, and with all the resources of a fertile and well stored mind. He entitled his book "Truth cleared of Calumnies." Though bearing the marks of a "prentice hand," many of the qualities of his later style are found in this production. William Penn says "It is written with strength and moderation." If the reader is disposed to question the moderation, he must remember the habits of the age.[14] [14] There is in this work an interesting passage ("Truth Triumphant" pp. 29, 30), in which the view of singing held by the early Friends is set forth, which will correct some mistaken impressions. Barclay maintains "that singing is a part of God's worship, and is warrantably performed amongst the saints, is a thing denied by no Quaker so-called, and is not unusual among them, whereof I have myself been a witness, and have felt the sweetness and quickening virtue of the spirit therein, and at such occasions ministered." But they object to a mixed congregation of believers and unconverted persons singing words which in the mouths of many must be lies. (See also the Apology, Prop. II., paragraph 26, &c.) But once launched on the stormy sea of controversy, there was no more rest for him. W. Mitchell acknowledged the authorship of the "Dialogue," and returned to the attack in some "Considerations." This drew forth in rejoinder "William Mitchell unmasked," published 1672. Here we find a more mature style, a fulness of matter, and an ease and power in statement, that are only excelled in the Apology. Says the writer in the Biographia Brittanica: "In this work our author discovers an amazing variety of learning; which shows how good a use he made of his time at Paris, and how thorough a master he was of the scriptures, the fathers, and ecclesiastical history; and with how much skill and judgment he applied them." And a recent writer says "Poor William Mitchell is not only unmasked but extinguished."
