Neumann joined a religious order, the Redemptorists, to help his own spiritual life and to have the support of a like-minded community. Even though the notorious "Know Nothing" Party tried to hinder his work, Neumann established the practice of the "40 Hours" devotion throughout the Philadelphia diocese. That Eucharistic devotion endures today not only in Philadelphia but thoughout the USA. Mother Seton began private Catholic schools. To reinforce catechetical learning and provide solid education to young Catholics, Neumann organized the parochial Catholic school system in his vast diocese. Millions of young people benefited from the schools Neumann and his successors founded in Pennsylvania and beyond.
The long-lasting famous Baltimore Catechism owed much to the contributions of Neumann.
Neumann was a man of deep prayer, self discipline and great kindness.
The Church of St. Peter at 5th and Girard in Philadelphia houses the Shrine of St. John Neumann. http://www.stjohnneumann.org/saint.html
