A classis is a group of churches within a geographical area that comes together to seek, discern, and submit to God's will, offer one another mutual support and accountability, find ways to live out a collective calling in the region, and allow for a healthy and sustained connection to the wider denomination.

A classis has the authority to deal with matters that concern its churches in common and its decisions are binding on the churches in its region. A minister, elder, and deacon from each congregation are delegated to attend each classis meeting.

Our Church Order defines classis in this way: "A classis is a group of Christian Reformed churches that come together to seek, discern, and submit to God’s will; offer one another mutual support and accountability; find ways to live out a collective calling within their region; and allow for a healthy and sustained connection to the wider denomination. A classis shall consist of a group of neighboring churches. The organization of a new classis and the redistricting of classes require the approval of synod."

Classis Renewal

Workshops for Classis

A variety of 60 minute workshop opportunities are available to help support your work in classis.

Resources for Classis Renewal

There is an online shared drive that houses many resources and documents related to gatherings, presentations, etc., including a folder with copies of current and past classis ministry plans.

Your classis can be supported by having a ministry plan in place. The types of ministry plans that classes have are diverse in content and approach, but they are all designed to help the classis flourish. See the above link for samples of classis ministry plans.

You can access a variety of resources and articles for classis on the Network.

Classes in the CRC

There are 49 classes in the CRC, 11 in Canada and 37 in the United States, and one with congregations on both sides of the border.

For denominational ministry services, classes are divided into six regions and their subregions (view as a printable PDF).(For representation on the Calvin University board, classes are divided into 6 regions, and for Calvin Theological Seminary boards, classes are divided into 12 regions.)
