Grace Covenant Church adheres to the basic principles of the Protestant Reformation regarding the Holy Bible as the Word of God as the only perfect rule for faith, doctrine, and conduct. It also values the historic confessions of the Christian church, particularly the Apostles' Creed. The doctrine of justification by personal faith in Jesus Christ as Savior and Lord is of paramount importance. Baptism and the Lord's Supper are divinely ordained sacraments of the church.

Consistent with its affirmation of classical Christianity and its own historical experience, Grace Covenant Church affirms as central to its life and thought a number of evangelical emphases. Foremost among these are the following:

The centrality of the Word of God.

The necessity of the new birth.

The church as a fellowship of believers.

A conscious dependence on the Holy Spirit.

The reality of freedom in Christ.
