Paul's statement about baptizing only Crispus and Gaius underscores his primary mission of preaching the gospel rather than performing baptisms. In the early church, there was a tendency for divisions to arise based on who baptized whom, which could lead to factions within the community. By minimizing his role in baptizing, Paul seeks to prevent such divisions and redirect the focus to the central message of Christianity: the life, death, and resurrection of Jesus Christ.
Paul's approach serves as a reminder that the power of the Christian faith lies not in human leaders or specific rituals, but in the transformative message of the gospel. This message transcends individual personalities and practices, urging believers to unite under the common banner of faith in Christ. By doing so, Paul encourages the Corinthian church, and all Christians, to prioritize their shared beliefs and the unity that comes from being part of the body of Christ. This unity is essential for the strength and witness of the church in the world.
