Saint Alphonsus Liguori, founder of the Redemptorists, provides programs of prayers and meditations for thirty-one visits to the Blessed Sacrament. Each day he offers devotional and inspirational material for eucharistic adoration, spiritual communion, and prayer. At the end of each visit Alphonsus gives material for a visit to the Blessed Virgin Mary. The saint also includes two hymns. His book draws widely from the writings of the saints. Alphonsus relinquished a career as a lawyer in order to respond to his vocation to study for the priesthood. In Naples he worked especially with the poor, and he established evening chapels for young people in the city. While serving as bishop he wrote many books and articles. Alphonsus was canonized by Pope Gregory XVI in 1839 and declared a Doctor of the Church in 1871.
