King James Bible
"And we believe and are sure that thou art that Christ, the Son of the living God."
Peter expresses both faith and certainty, moving beyond mere intellectual assent to deep conviction. This declaration comes after many disciples abandoned Jesus (v. 66), highlighting the apostles' contrasting steadfast commitment. The disciples recognize Jesus as the promised Messiah (Christ meaning "anointed one"). This acknowledgment affirms Jesus fulfills the Old Testament prophecies of a coming deliverer who would establish God's kingdom. This title elevates Jesus beyond human messianic expectations to divine sonship. The phrase "living God" contrasts with lifeless idols and emphasizes God's active, life-giving nature—which Jesus uniquely shares and manifests.
