What does it mean that apostles were eyewitnesses of Christ?

The apostles claimed to be eyewitnesses of Christ, which is a critical aspect of their authority and the authenticity of the Gospel. This claim reinforces their messages and teachings, as they not only heard Christ but also witnessed His miracles, crucifixion, and resurrection firsthand. In 1 Corinthians 15:6, Paul emphasizes that Jesus appeared to over 500 people after His resurrection, strengthening the credibility of the apostles’ testimonies. Their unique position as eyewitnesses is integral because it assures believers that the teachings regarding Christ’s nature and work are rooted in firsthand experience, vital for understanding the fullness of the Gospel.
