A Common Theological Core
One of the founding principles of ECO was uniting pastors and congregations around a common theological core. The goal is not to be same-minded, but like-minded. We affirm that theological consensus around certain essentials is foundational for a healthy denomination. As a covenant community, our unity derives from a clearly-articulated theology that is Christ-centered, Reformed, and evangelical.
The ECO Polity, in The Constitution, outlines our behavioral and theological essentials and requires that all officers “receive, adopt, and be bound by” these essentials tenets.
We offer curricula to equip leaders to teach the Reformed faith in their congregations.
The goal is for more people to know — and apply — God’s Word in daily life. We believe churches flourish when both leaders and members engage in thoughtful theological reflection. One of the treasures of the Reformed heritage is an emphasis on theological education, constant learning, and the life of the mind.
