The IECD believes in one eternal God in three persons: Father, Son, and Holy Spirit. God is sovereign, holy, and just. The Bible, inspired and infallible, is the ultimate authority. Humans, created in God’s image, are corrupted by sin and need redemption through Jesus Christ, who is fully God and man. Salvation, by grace through faith in Christ, brings forgiveness and eternal life. The Holy Spirit indwells believers, empowering them for service. The universal Church, led by Christ, expresses unity in local congregations. Baptism and the Lord’s Supper symbolize the gospel. Jesus will return to judge and renew all creation.
