The Holy Spirit is elusive, has no name or face.

When looking for arguments that allow to approach his mystery, a really important thing arises: is every person who gives the Spirit face when living under his guidance within the ecclesial tradition.

Throughout these pages the author invites to approach the Spirit from different perspectives whose common denominator is the relationship. Thus the Spirit is contemplated in the midst of the Trinity, acting in the Church, exercising his spiritual paternity or being traveling companion in the Christian life.

The Holy Spirit, confessed in the creed as the third person of the Trinity, continues to act in history with overflowing vitality through martyrdom and prophecy, beauty and love, contemplation and commitment.

Olivier Clément (1921-2009) was professor of theology at St. Sergius Institute in Paris and one of the main representatives of the tradition of the Orthodox Church in the West.
