Imprisoned (as he put it himself) “merely for preaching the Gospel, as he had received power from Christ”, William Erskine would certainly preach again to the benefit of many. His cousins Ralph and Ebenezer are better known but the little we can learn about "honest Mr William Erskine" gives evidence of a resolute Covenanter. We visit the building where he preached: Tron Church, Edinburgh, sadly no longer used as a church.
