The Holy Spirit is the soul of the Church. Without him what would she be reduced to? She would certainly be an important movement in history, a complex and solid social institution, perhaps a sort of humanitarian agency. And to tell the truth she is considered such by those who do not see her from a perspective of faith. Yet, the reality is that in her true nature and also in her authentic presence in history, the Church is ceaselessly formed and guided by the Spirit of her Lord. She is a living body, whose vitality is, precisely, the fruit of the invisible divine Spirit.
