A strong case can be made for holding that Chapter Five of Lumen Gentium presents the most important and innovative, and even the most revolutionary doctrine of the Second Vatican Council. Under the title of "The Universal Call to Holiness", a totally personalized message is presented to each member of the Church. Each in effect, whatever his or her position in life, is called to sanctity, to the fullness of friendship and intimacy with God. To help each one become truly aware of what this implies and to help each to see and use the ways and means of responding effectively to this personal call from God, remains a top priority in the ongoing work of ecclesial renewal.
