The new priory’s role in the community was most important to the local Catholic population, which at the time was approximately 700: “Father Larkin recalled the need of Catholic education so pressing in Adelaide at the opening of this century, and the need of intensive religious instruction to compensate for the lack of a completely Catholic system of education.”
The Dominican Fathers were much in demand and were asked to care for the whole diocese, travelling as far as Mount Gambier to give missions. Their own parish was divided into three districts, with each Father being responsible for one part. The three districts were approximately the North Adelaide district, the Prospect district, and beyond to the Kilburn area. Father Larkin later described how valuable was visitation for maintaining communication between laity and clergy, and as a means of bringing back the wayward and making converts.
