Book excerpt: Unity, joy, simplicity, beauty, truth—these are the hallmarks of the three Persons in one God, the Trinity. In Contemplating the Trinity, Fr. Raniero Cantalamessa, the preacher to the papal household, invites readers to turn to the Trinity so that they can enter into and experience the relationship of love that the divine Persons share with one another. Convinced that Christians today need a spirituality that is more clearly trinitarian, Fr. Cantalamessa draws from theology, spirituality, and art to articulate this new perspective and its implications. As readers accept Christ’s invitation to immerse themselves in the “bottomless sea without shores” that is the Trinity, they will find themselves on a journey that promises a deeper understanding of how this relationship of love can be our standard for holiness.
