Life in Christ›SECTION ONE MAN'S VOCATION LIFE IN THE SPIRIT›CHAPTER THREE GOD'S SALVATION: LAW AND GRACE›Article 3 THE CHURCH, MOTHER AND TEACHER
The moral life is spiritual worship. We "present (our) bodies as a living sacrifice, holy and acceptable to God," within the Body of Christ that we form and in communion with the offering of his Eucharist. In the liturgy and the celebration of the sacraments, prayer and teaching are conjoined with the grace of Christ to enlighten and nourish Christian activity. As does the whole of the Christian life, the moral life finds its source and summit in the Eucharistic sacrifice.
