Each chapter places the given passage in its larger historical context, explores its fundamental meaning and significance, and finally considers its larger significance for the life of the church today. Chapters include exploration of Sacrosanctum Concilium's demand for full, conscious, and active participation in the liturgy; Lumen Gentium's eucharistic ecclesiology; Gaudium et Spes's vision of marriage as an intimate partnership of life and love; Nostra Aetate's approach to non-Christian religions; and more.
