Ligonier Ministries is a Reforme, evangelical, non-profit organization headquartered in the greater Orlando area. Founded by R. C. Sproul in the Ligonier valley outside of Pittsburgh over thirty-five years ago, Ligonier's stated purpose is "to awaken as many people as possible to the holiness of God by proclaiming, teaching, and defending God’s holiness in all its fullness."[cite this quote] Sproul and Ligonier are particularly known for their teaching of Covenant Theology, of which Calvinism is an important facet.
