What is the content of the faith that all believers share?

The faith referred to in Scripture is not merely subjective beliefs but encompasses a definite content, as exemplified in Titus 1:1, where it is called 'the faith of God's elect.' This common faith upholds essential doctrines regarding God's nature, humanity's sinfulness, and the sufficiency of Christ for salvation. All believers acknowledge these truths, uniting them beyond denominational lines. Moreover, this unity speaks to the need for biblical doctrine to be upheld faithfully—a reminder that the shared belief in Christ as both Savior and Lord is what truly defines the community of faith. John's description of faith in Revelation 13:10 reflects this unity, detailing a collective reliance on Christ’s redemptive work presented in the gospel.
