We believe the Church is marked primarily by submission to the Scriptures. The Bible is the pure Word of God, the only absolute authority for Christians, and all things within the church are governed/managed accordingly. As a broadly Reformed family of churches, we affirm three marks of a true church:  (1) the faithful preaching and teaching of the Word, (2) the faithful administration of the Sacraments (Baptism and the Lord's Supper), and (3) the faithful exercise of church discipline.

Southside Fellowship Confession of Faith receives the Nicene Creed, The BFM 2000, the Gospel Coalition Confessional Statement, and the 5 doctrinal distinctives of the Acts 29 Network. Although we do not require our members to agree on every point, the confession forms the theological identity of Southside Fellowship.
