Christian Reformed Church

Our Faith

We believe that the Old and New Testaments are the inspired Word of God, the only infallible rule for faith and life. We af?rm three creeds—the Apostles’ Creed, the Nicene Creed, and the Athanasian Creed—as ecumenical expressions of the Christian faith. ? Read More....

What is a Classis?

Classis comes from the ancient Latin word "classis," and in one of its uses refers to a "fleet of ships."  The original purpose of a classis was largely the- logistical movement of personnel and support; and to keep open communication routes across great expanses of water, or landscape separated by water.  Read More...

You could ask, “What difference does being Reformed really make”? A Reformed identity is much more than a set of theological principles. It’s a biblically based framework for building a life that is deep and rich, shaped by the knowledge that, as the Heidelberg Catechism says, “I am not my own, but belong—body and soul, in life and in death—to my faithful Savior Jesus Christ” (Q&A 1).

To answer this question, consider how a Reformed identity shapes a life*:

  • You have a firm confidence that you live by Grace alone.
  • You recognize that Jesus is Lord.
  • You understand that God’s story shapes the story of your life.
  • You see God in all of creation.
  • You recognize you are created in God’s image.
  • You understand the complete devastation sin creates.
  • You trust in God’s providential care.
  • You belong to a worshiping community.
  • You are set free to live honestly.
  • You become God’s partner in making all things new.

God's Kingdom without Borders

As the Christian Reformed Church in North America, we are called to express the good news of God’s kingdom that transforms lives and communities.

We seek to carry out this calling individually and as congregations. And we join with each other through regional assemblies (called classes) and denominational ministries, in the firm belief that together we can do more.
