Barclay, Robert, the celebrated apologist of Quakerism, born in Morayshire; tempted hard to become a Catholic; joined the Society of Friends, as his father had done before him; his greatest work, written in Latin as well as in English, and dedicated to Charles II., “An Apology for the True Christian Divinity, as the same is held forth and preached by the People called in scorn Quakers,” a great work, the leading thesis of which is that Divine Truth is not matter of reasoning, but intuition, and patent to the understanding of every truth-loving soul (1645‒1690).
