Ryken, like most of the early Xaverian Brothers, was trained as a shoemaker. However, Ryken also felt a calling by God which impelled him to work first as a catechist, then in helping to conduct an orphanage, and again in caring for cholera patients in the Netherlands.
Aged 34, Ryken went to North America and served as a catechist among the missionaries to the Native Americans. During his three year tour, he conceived the idea of starting a congregation of brothers to work alongside the missionary priests. On returning to Europe he set about planning the establish such a society in Belgium, a country eminent for missionary zeal.
Ryken prepared for a journey to Rome to receive the permission and blessing of Pope Gregory XVI by going through a term of probation in the novitiate of the Redemptorist Fathers. This influenced him to model the religious garb of his order after that of the Redemptorists. The spirit of the Xaverian Brothers, on the other hand, can be traced to the influence of the Jesuit confessor and counselor of Ryken, Rev. Isidore Van de Kerckhove, who drew up the original rules. Although many religious institutes were being founded at the time as part of a revival that succeeded the fall of Napoleon I, Ryken's vision was different. He wanted to found a missionary institute rather than a congregation that would address the needs of a specific region.
On June 15 1839, Ryken, then 42 years old, went to live in a rented house on Ezelstraat in the centuries old city of Bruges, Belgium. For five long days the founder waited for the arrival of the two companions who had promised to join him in his undertaking: a weaver and a tailor. Unfortunately for Ryken, his companions would prove less dedicated and resilient than himself and it took a year before better suited candidates were welcomed into the house on Ezelstraat. Two primary schools were soon opened in Bruges, and some brothers were sent to a normal school at Sint-Truiden for professional training.
By 1841, the community had grown beyond the space available in the little house on Ezelstraat, and Ryken, with financial help from a sympathetic banker, purchased a large estate in a neighboring section of Bruges called "Het Walletje". The Xaverian brothers began to attract candidates from Germany, the Netherlands, Belgium, England, Ireland and France.
In 1848, a colony of brothers went to England to open schools in parishes in Bury and Manchester. Eventually, they opened Clapham College, London.
Before his death on November 26 1871, aged 74, Ryken was present at the first general chapter of his order in Bruges in 1869. By this time the debt had been cleared and the number of brothers had grown from 58 in 1860 to 133, and there were nine well-established communities working among the poor in Belgium, England and the United States.
In 1864, Spalding, then Archbishop of Baltimore, asked the Xaverians to open schools there, and they did so. Baltimore was made the center of Xavierian activities in the United States, and in 1876 a novitiate was opened there at the site of Mount Saint Joseph High School, where it still stands.
By 1900, the Xaverian Brothers had opened schools in New York, Maryland, Massachusetts, Virginia, West Virginia, and Pennsylvania.
Inspired by the message of Our Lady of Fatima, Mattingly formed "Our Lady of Fatima Rosary Making Club" in the basement of St. Xavier High School in Louisville in 1949. Although Mattingly died in 1951, the organization grew to be Our Lady's Rosary Makers which has 17,000 active members in the United States and has distributed hundreds of millions of free rosaries worldwide.
