Quick Summary

Lumen Gentium, meaning "Light of the Nations," is a key document from the Second Vatican Council in Roman Catholicism. It describes the Church as the "mystical body of Christ," a spiritual union of all Christians with Jesus as their head. This concept, rooted in the New Testament, emphasizes that Christ came to offer salvation to everyone, suggesting all people are, at least potentially, members of the Church. The document also redefined the role of the laity, encouraging their greater participation in church life and recognizing their proper sphere of action in the secular world.123
