Catechism of the Catholic Church

The Father's self-communication made through his Word in the Holy Spirit, remains present and active in the Church: "God, who spoke in the past, continues to converse with the Spouse of his beloved Son. And the Holy Spirit, through whom the living voice of the Gospel rings out in the Church-and through her in the world-leads believers to the full truth, and makes the Word of Christ dwell in them in all its richness."
