About Three Forms Resources

What Are the Three Forms of Unity?

The Three Forms of Unity are the primary confessional documents of Reformed churches worldwide. They include:

The Heidelberg Catechism (1563) - A catechism of 129 questions and answers teaching Reformed doctrine through the themes of guilt, grace, and gratitude.
The Belgic Confession (1561) - A confession of 37 articles articulating the Reformed faith in the face of persecution.
The Canons of Dort (1619) - The Five Points of Calvinism affirmed by the Synod of Dort in response to Arminianism.

Why Study the Three Forms?

These historic confessions help Christians understand and articulate biblical doctrine. They provide a framework for systematic theology, guide pastoral ministry, and unite believers across generations in shared doctrinal commitments.

Our Mission

Three Forms Resources exists to serve the Church by making it easier to discover high-quality materials for studying these foundational Reformed documents. We carefully catalog books, commentaries, study guides, sermons, and other resources to help pastors, teachers, students, and laypeople grow in their understanding of Reformed theology.
