Historic Standards of the Reformed Faith
Confessions & Catechisms
"The church is the pillar and buttress of the truth." — 1 Timothy 3:15
The Reformed tradition has always expressed its faith in written confessions — not as rivals to Scripture, but as faithful, tested summaries of what Scripture teaches. These subordinate standards carry real authority in the church precisely because, and only insofar as, they agree with the Word of God.
Confessions are subordinate standards — they carry real authority within the church, but always under Scripture. The Westminster Confession itself says: "The Supreme Judge, by which all controversies of religion are to be determined… can be no other but the Holy Spirit speaking in Scripture." The confessions are not the final word; they are faithful witnesses to the One who is.

Westminster Standards
The Westminster Standards are the defining confessional documents of the Presbyterian tradition, produced by the Westminster Assembly (1643–1649) — a gathering of over 120 English and Scottish divines convened by the English Parliament. They represent the most thorough and systematic expression of Reformed soteriology, ecclesiology, and ethics in the English language, and remain the subordinate standards of most Presbyterian denominations worldwide.
Westminster Confession of Faith
The Westminster Confession of Faith (1646) is a thirty-three chapter systematic exposition of Reformed doctrine, organized from the doctrine of Scripture (Chapter 1) through the last judgment (Chapter 33). It covers the doctrines of God, the covenant of works, the fall, the covenant of grace, justification, sanctification, the church, the sacraments, and the civil magistrate. It is the most comprehensive single confessional statement of the Reformed faith ever produced.
Westminster Larger Catechism
The Westminster Larger Catechism (1647) consists of 196 questions and answers intended for the instruction of adults and for public use in worship. Its treatment of the Ten Commandments (Q. 91–148) and the Lord's Prayer (Q. 178–196) is among the most thorough in any confessional document. It also provides one of the fullest treatments of the covenant of redemption and effectual calling in a catechetical format.
Westminster Shorter Catechism
The Westminster Shorter Catechism (1647) consists of 107 questions and answers written for the instruction of children. Its opening exchange is among the most celebrated sentences in the history of Christian theology:
Q. What is the chief end of man?
A. Man's chief end is to glorify God, and to enjoy him forever.
The WSC covers the same ground as the Confession in miniature: the Apostles' Creed (Q. 1–38), the Ten Commandments (Q. 39–84), and the Lord's Prayer (Q. 85–107). It remains one of the most widely memorized catechisms in the Protestant world.
Dutch Reformed Tradition · 16th–17th Century
Three Forms of Unity
The Three Forms of Unity are the confessional standards of the continental Reformed (Dutch) tradition: the Belgic Confession, the Heidelberg Catechism, and the Canons of Dort. Together they define the doctrinal boundaries of the Dutch Reformed and Christian Reformed churches worldwide. Each of the three documents addresses a different dimension of the faith — apologetic defense, pastoral catechesis, and polemical precision — and together they provide one of the most balanced and comprehensive confessional frameworks in Protestantism.
Belgic Confession
Guido de Brès, 1561 · 37 Articles
The Belgic Confession was written by Guido de Brès in 1561 — partly to distinguish Reformed Christians from Anabaptists, partly to appeal to Philip II of Spain for toleration of Reformed worship in the Netherlands. De Brès was martyred in 1567. The Confession covers the nature of Scripture, the Trinity, creation, the fall, election, the two natures of Christ, justification by faith alone, the church, the sacraments, and the civil magistrate in thirty-seven articles.
Heidelberg Catechism
Zacharias Ursinus & Caspar Olevianus, 1563 · 129 Q&A
The Heidelberg Catechism, commissioned by Elector Frederick III of the Palatinate and primarily written by Zacharias Ursinus, is among the most beloved catechisms ever produced. It is organized around three themes — guilt, grace, and gratitude — and is notable for its warmly pastoral and personally engaging tone. Its very first question sets the tone for the whole:
Q1. What is your only comfort in life and in death?
A. That I am not my own, but belong — body and soul, in life and in death — to my faithful Savior, Jesus Christ…
The catechism is divided into fifty-two Lord's Days for weekly reading through the year. Its treatment of the Apostles' Creed (Lord's Days 7–22), the sacraments (22–30), and the Ten Commandments and Lord's Prayer (34–52) has made it a perennial favorite for both congregational and family instruction.
Canons of Dort
Synod of Dort, 1618–1619 · 5 Heads of Doctrine
The Canons of Dort were produced by the international Synod of Dort (1618–19), convened to address the Arminian Remonstrance — a five-point challenge to Reformed soteriology presented by the followers of Jacob Arminius in 1610. The Synod, attended by delegates from Reformed churches across Europe, responded with five heads of doctrine that became the basis for the TULIP acrostic. The Canons are more detailed and more carefully nuanced than the acrostic suggests, addressing objections and pastoral concerns at length.
Catholic Orthodoxy · 2nd–5th Century
Ecumenical Creeds
Before there were Reformed confessions, there were the ecumenical creeds — summaries of Christian orthodoxy recognized across all branches of the historic church. The Reformed tradition gladly receives these creeds as faithful summaries of biblical teaching, binding on the church not because of their antiquity but because they accurately reflect what Scripture teaches about the Trinity, the incarnation, and the resurrection. They are the foundation on which the Reformation built.
Apostles' Creed
c. 2nd century, reaching its current form by c. 700
The Apostles' Creed is the oldest and simplest of the three ecumenical creeds. Though not written by the apostles themselves, it derives from the baptismal confession used in early Roman Christianity and faithfully summarizes apostolic teaching. It is structured Trinitarianly — Father (creation), Son (redemption), and Spirit (the church, resurrection, eternal life) — and is used in baptismal vows, daily prayer, and congregational worship across the Reformed tradition.
I believe in God the Father Almighty, Maker of heaven and earth; and in Jesus Christ, his only Son, our Lord… I believe in the Holy Ghost; the holy catholic church; the communion of saints; the forgiveness of sins; the resurrection of the body; and the life everlasting. Amen.
The Heidelberg Catechism (Q. 23–58) expounds the Apostles' Creed in full.
Nicene Creed
Council of Nicaea 325; expanded at Constantinople 381
The Nicene Creed was produced to defend the full divinity of the Son against Arianism, which held that the Son was a created being — the highest creature, but a creature nonetheless. The Council of Nicaea (325) declared the Son to be homoousios ("of the same substance") as the Father. The expanded form from Constantinople (381) added the full deity of the Spirit. The Nicene Creed is the most widely used creed in Christendom, used in the Eucharist of Catholic, Orthodox, Anglican, Lutheran, and Reformed churches.
Athanasian Creed
c. 5th century · Quicumque Vult
Despite bearing Athanasius's name, the Athanasian Creed (also called Quicumque Vult — "Whoever wishes to be saved") was likely composed in Latin in southern Gaul in the late fifth century. It is the most detailed of the three creeds, providing the most precise and philosophically careful exposition of the Trinity and the two natures of Christ in any creed. Its dual focus — getting the Trinity right and getting the incarnation right — reflects the two great dogmatic battles of the patristic era (Arianism and Nestorianism/Eutychianism).
"We worship one God in Trinity, and Trinity in Unity; neither confounding the persons, nor dividing the substance."
Why the Creeds Matter for Reformed Christians
The Reformation was not a rejection of catholic orthodoxy — it was a recovery of it. Luther, Calvin, and the Reformed confessions all embraced the Trinitarian and Christological definitions of the early councils as faithful expositions of Scripture. The Five Solas are not intelligible without the Nicene foundation: it is the God of Nicaea — fully triune, the Son fully divine — whose grace alone, in Christ alone, justifies by faith alone. Creedal orthodoxy and Reformed soteriology are not competitors; they are the same gospel at different levels of resolution.
Subordinate Standards
Confessions Serve Scripture
Every confession and catechism on this page carries authority only insofar as it faithfully reflects the Word of God. The Reformers did not trade papal authority for confessional authority — they submitted all authorities to Scripture. These documents are guides and guardrails, not lords.
