CCC 688 The Church, a communion living in the faith of the apostles which she transmits, is the place where we know the Holy Spirit:
– in the Scriptures he inspired;
– in the Tradition, to which the Church Fathers are always timely witnesses;
– in the Church’s Magisterium, which he assists;
– in the sacramental liturgy, through its words and symbols, in which the Holy Spirit puts us into communion with Christ;
– in prayer, wherein he intercedes for us;
– in the charisms and ministries by which the Church is built up;
– in the signs of apostolic and missionary life;
– in the witness of saints through whom he manifests his holiness and continues the work of salvation.
