How do we know that Christ crucified is central to our faith?

The emphasis on Christ crucified is evident throughout the New Testament, especially in Pauline epistles. Paul states in 1 Corinthians 1:23 that he preaches Christ crucified, which is a stumbling block to some and foolishness to others, yet it is the power of God for those who believe. This reinforces that the acknowledgment of Christ's sacrifice is not just an aspect of faith but is integral to understanding God's redemptive plan. Every doctrine in Christianity is rooted in the truth of Christ's atonement and His fulfillment of Old Testament prophecies regarding sin and salvation.
