Check out this interview from 2007 in the journal 30Giorni. Money quote:
"The early theologians said: the soul is a kind of sailing boat, the Holy Spirit is the wind that blows in the sail, to send it on its way, the impulses and the force of the wind are the gifts of the Spirit. Without His drive, without His grace, we don’t go ahead. The Holy Spirit lets us enter the mystery of God and saves us from the danger of a gnostic Church and from the danger of a self-referential Church, leading us to the mission."
