Thomas Aquinas is widely considered the greatest and most influential of Catholic theologians. Yet too often his insights into the nature of God and the meaning of life are seen as somehow cold, impersonal, and divorced from spirituality. In this award-winning book, Bishop Robert Barron shows how Aquinas' profound understanding of the Christian mystical life animates and helps explain his writings on Jesus Christ, creation, God's ';strange' nature, and the human call to ecstasy. ';When one interprets Thomas merely as a rationalist philosopher or theologian, one misses the burning heart of everything he wrote. Aquinas was a saint deeply in love with Jesus Christ, and the image of Christ pervades the entire edifice that is his philosophical, theological, and scriptural work. Above all, Thomas Aquinas was a consummate spiritual master, holding up the icon of the Word made flesh and inviting others into its transformative power.'
