Here, in speaking of the Holy Spirit, Jesus explains to us what the Church is and how she should live in order to be herself, to be the place of unity and communion in Truth; he tells us that behaving as Christians means no longer being shut into our own “I” but rather being open to all things: it means inwardly welcoming the whole Church within ourselves or, even better, inwardly letting her receive us. Therefore when I speak, think and act as a Christian I do not do so by closing myself into myself, but I always do so in all things and starting with all things: thus the Holy Spirit, the Spirit of unity and of truth, may continue to resonate in our human hearts and minds and spur people to meet and to welcome each other.

Precisely because the Spirit acts in this way, he ushers us into the whole truth, which is Jesus, and guides us to look at it more deeply and to understand it. We do not grow in knowledge by locking ourselves into own ego but only in an attitude of profound inner humility do we become capable of listening and sharing in the “we” of the Church. And in this way it becomes clearer why Babel is Babel and Pentecost is Pentecost. Wherever people want to set themselves up as God they cannot but set themselves against each other. Instead, wherever they place themselves in the Lord’s truth they are open to the action of his Spirit who sustains and unites them.

[Pope Benedict, homily 27 May 2012]
