Creeds & Confessions of the Church

Searchable creeds, confessions, and catechisms of the church.

The Ecumenical Creeds

• The Apostles’ Creed
• The Nicene Creed
• The Athanasian Creed

The Westminster Standards

• The Westminster Confession of Faith
• The Westminster Shorter Catechism
• The Westminster Larger Catechism

Each of these carries the OPC lettered scripture proofs in collapsible callouts, and can be read either in the constitutional text or in the 2025 Modern English Study Version — use the toggle in the toolbar. The MESV is for study only and carries no constitutional authority.

The Three Forms of Unity

• The Belgic Confession
• The Heidelberg Catechism
• The Canons of Dort

The OPC Book of Church Order

• The Form of Government
• The Book of Discipline
• The Directory for the Public Worship of God

Scripture Index

The confessions cite scripture; the scripture index reads the other way. Look up a book of the Bible and see every section of the Westminster Standards and the Heidelberg Catechism that cites it.
