The Holy Cross Brothers took him into the novitiate but soon found out what others had learned – as hard as Alfred (now Brother André) wanted to work, he simply wasn't strong enough. They asked him to leave the order, but André, out of desperation again, appealed to a visiting bishop who promised him that André would stay and take his vows as a Religious Brother.
After his vows, Brother André was sent to Notre Dame College in Montreal (a school for boys age seven to twelve) as a porter. There his responsibilities were to answer the door, to welcome guests, find the people they were visiting, wake up those in the school, and deliver mail.
In 1904, he surprised the Archbishop of Montreal by requesting permission to build a chapel to Saint Joseph on the mountain near the college. The Archbishop refused to go into debt and would only give permission for Brother André to build what he had money for. What money did Brother André have? Only the nickels he had collected as donations for Saint Joseph from haircuts he gave the boys; nickels and dimes from a small dish he had kept in a picnic shelter on top of the mountain near a statue of St. Joseph with a sign "Donations for St. Joseph." He had collected this loose change for years but he still had only a few hundred dollars. Who would start a chapel now with so little funding?
André took his few hundred dollars and built what he could – a small wood shelter only fifteen feet by eighteen feet. He kept collecting money and went back three years later to request to do more building. The Archbishop granted him permission to keep building as long as he didn't go into debt. He started by adding a roof so that all the people who were coming to hear Mass at the shrine wouldn't have to stand out in the rain and the wind. Then came walls, heating, a paved road up the mountain, a shelter for pilgrims, and finally a place where Brother André and others could live full-time to take care of the shrine and the pilgrims who came.. Through kindness, caring, and devotion, Brother André helped many souls experience healing and renewal on the mountaintop. There were even cases of physical healing. But for everything, Brother André thanked St. Joseph.
Despite financial troubles, Brother André never lost faith or devotion. He had started to build a basilica on the mountain but the Depression had interfered. When he was ninety years old he told his co-workers to place a statue of St. Joseph in the unfinished, unroofed basilica. He was so ill he had to be carried up the mountain to see the statue in its new home. Brother André died soon after on January 6, and didn't live to see the work on the basilica completed. But he died in peace, having helped hundreds of thousands of people by strengthening their faith, and by giving honor to the foster-father of our Lord.
O God, whose blessed Son became poor that we through his poverty might be rich: Deliver us, we pray thee, from an inordinate love of this world, that, inspired by the devotion of thy servant, St. André Bessette, we may serve thee with singleness of heart, and attain to the riches of the age to come; through the same thy Son Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
