Throughout the history of Christendom, the Lord’s Prayer has held a special place of honor. Nicholas Ayo’s The Lord’s Prayer presents a carefully detailed exposition of the Our Father as a text worthy of inspiring both mind and heart. Ayo’s approach combines a word-by-word biblical and exegetical study and includes an anthology of patristic and modern commentary on the Lord’s Prayer, drawn from Origen, Thomas Aquinas, Teresa of Avila, and Simone Weil, among others. In addition, he provides historical analysis, critical evaluation, and discussion of the deeper issues raised by the various interpretations of the Lord’s Prayer. Finally, Ayo includes a personal meditation on the overall significance of this unique prayer in the spiritual life.
