The Unity of The Church is about the unity of the faith. The unity of the faith is about the basic beliefs of the Christian faith-what is foundational-about God and man and good and evil. The unity of the faith is not about making converts. It is not about what is fundamental for initial conversion, for being saved, or for entering into the kingdom of God. It is about what is foundational, which is necessary for maturity in Christ. Foundation is for fullness, and what is maximal includes what is minimal. Unity of the faith is not to be equated with the unity of the Spirit in professing one Lord, one faith, one baptism, which already exists among believers and is to be preserved in the bond of peace. Unity of the faith is about the fullness of Christ to be attained, as mentioned in Ephesians 4:13.
