Seeing a unique opportunity for good, Canon de La Salle resigned his canonry, gave his inheritance to the poor, and began to organize his teachers into a religious congregation. Soon, boys from his schools began to ask for admission to the Brothers, and the founder set up a juniorate to prepare them for their life as religious teachers. At the request of many pastors, he also set up a training school for teachers, first at Rheims, then at Paris, and finally at St.-Denis. Realizing that he was breaking entirely new ground in the education of the young, John Baptist de la Salle wrote books on his system of education, opened schools for tradesmen, and even founded a school for the nobility, at the request of King James II of England.
The congregation had a tumultuous history, and the setbacks that the founder had to face were many; but the work was begun, and he guided it with rare wisdom. In Lent of 1719, he grew weak, met with a serious accident, and died on Good Friday. He was canonized by Pope Leo XIII in 1900, and Pope Pius XII proclaimed him patron of schoolteachers.
O God, who for the Christian education of the poor, and for the confirmation of the young in the way of truth, didst raise up the holy Confessor John Baptist de la Salle, and through him didst gather a new family in the Church: graciously grant that by his intercession and example we, being kindled with zeal for thy glory in the salvation of souls, may be enabled to be made partakers of his crown in heaven; 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.
