Samuel Rutherford (c. 1600–1661) was a Scottish Presbyterian minister and theologian. Pastor at Anwoth in Galloway, he was banished to Aberdeen for nonconformity, later became principal of St Mary's College, St Andrews, and sat as a Scottish commissioner at the Westminster Assembly. His Lex, Rex defended constitutional limits on kingship; but he is loved most for his Letters, written to suffering correspondents and treasured in our library alongside his sermons.

Samuel Rutherford's treatise on the trial and triumph of faith, published in 1645 while he was a leading figure of the Scottish church. Rutherford examines how God tests believing souls through affliction and apparent desertion, and how faith, though weak and wrestling, finally prevails through Christ. The writing bears the warmth and intensity for which his letters also became known.
