Robert Barclay

Born in Scotland in 1648, Robert Barclay became one of the most important writers in the early Religious Society of Friends, or Quakers. He was educated in Paris while still young, but after returning to Britain he embraced Quaker beliefs and quickly became known for his learning, calm reasoning, and ability to defend the movement in print.

Barclay is best remembered for An Apology for the True Christian Divinity (1678), a book that became the classic summary of Quaker theology. In it, he set out Quaker ideas with unusual clarity, arguing for the inward guidance of the Spirit and a direct, living faith rather than religion based only on outward forms. Because of this work, he is often seen as the movement's first great theologian.

He died in 1690 at Ury in Aberdeenshire. More than three centuries later, he is still read as a key voice in Quaker history and as a writer who gave a young religious movement a confident and thoughtful public defense.
