Catholic Home Study Service (CHSS), sponsored by the Missouri Knights of Columbus Religious Information Bureau, has been offering free courses on the Catholic Faith for more than seventy years. They help others gain a clearer knowlegde of Catholicism as a step toward becoming Catholic, or just to learn what we believe.
It is located on the campus of Saint Mary's of the Barrens, in Perryville, Missouri.
Rev. Father Oscar Lukefahr, C.M. is the Director of Catholic Home Study Service. Fr. Luke has served the CHSS and R.I.B. causes for many years.
