This study centres on Paul’s declaration, “But we preach Christ crucified,” showing the cross as the Church’s true point of unity. Writing to a divided Corinthian church, Paul directs believers away from personalities, pride, and shallow thinking, and back to Christ alone. The cross heals division, humbles human pride, and defines authentic Christianity as wisdom, righteousness, sanctification, and redemption found only in Christ. It is the heart of the gospel message and the glory of the Church. By glorying only in the cross, believers are united, transformed, and kept faithful to the truth in a distracted and superficial age.
