What is the common faith mentioned in Titus?

In Titus 1:4, Paul introduces the concept of common faith, which signifies a shared belief among the elect that originates from the same source—God's grace. This commonality is not about ordinariness but illustrates a unity in believing the same truths about salvation in Christ. Each member of the elect experiences God's grace, leading to a common acknowledgment of truth that glorifies God. This indicates that, despite individual differences, all believers are united in their faith and hope in the promises of God through Jesus Christ.
