Ordained to the priesthood in 1726, St. Alphonsus Liguori joined a group of secular priests dedicated to missionary activities. He involved himself in many kinds of pastoral activities, giving missions and organizing workers, and had a part in the founding of an order of contemplative nuns.
In 1732, he founded the Redemptorists, a congregation of priests and brothers, to work especially among the country people of Italy who often lacked the opportunity for missions, religious instruction, and spiritual retreats. His first companions deserted him, but Alphonsus stood firm, and soon vocations multiplied and the congregation grew.
The Redemptorists were approved by Pope Benedict XIV in 1749, and St. Alphonsus was elected superior general. In 1762, he was appointed bishop of Sant' Agata near Naples, and as bishop he corrected abuses, restored churches, reformed seminaries, and promoted missions throughout his diocese. During the famine of 1763-64, his charity and generosity were boundless, and he also carried on a huge campaign of religious writing.
In 1768, he was stricken with a painful illness and resigned his bishopric. During the last years of his life, problems in his congregation caused him much sorrow and when he died on August 1, 1787, at Pagani, near Salerno, the Congregation of the Redemptorists was in a state of division.
St. Alphonsus was beatified in 1816, canonized in 1839, and declared a Doctor of the Church in 1871.
O God, who didst inflame blessed Alphonsus, thy Confessor and Bishop, with zeal for souls, and didst through him enrich thy Church with a new offspring: we beseech thee; that being taught by his wholesome precepts and strengthened by his example, we may be enabled to attain in gladness unto thee; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
