This mission is conducted by the Dominican Friars. They are members of an order founded by St. Dominic de Guzman in 1216.

Saint Dominic was a priest, a canon of the cathedral of Osma in Spain, for eight years before becoming a missionary himself. Having to make a trip into the outside world one day, he discovered that many Christians had by ignorance fallen into a false kind of religion. He was so moved by their miserable condition that for the next fourteen years he preached the truths of Christ in season and out of season all through southern France. Realizing that individual priests here and there could do but little to bring the light of truth to darkened minds, he decided to expand his work and found a group of men united as a religious order whose work in life was to preach the truths of Christ.

The title "O.P." used by Dominicans means "Order of Preachers". It was conferred on them by Pope Innocent III and is the official name of the order. However, "Dominicans" is the more popular name and comes from the name of their founder.

Saint Dominic found that preaching was frequently a very disappointing task. One day while he was fervently praying to our Blessed Mother to assist him in this tremendous work, Mary appeared to him and taught him to pray the Rosary and told him to spread this devotion among the faithful. Her desires were fulfilled, and today the Rosary is one of the most common prayers in the Catholic Church. In the spirit and example of St. Dominic the Dominican missionaries will lead the Rosary before each service of this mission, for they are certain that if the faithful develop a strong devotion to the Blessed Virgin Mary by fervently and frequently praying the Rosary, their work as missionaries will be successful and the faithful of our day will come to know true Christian joy and to love the truths of Christian faith as did St. Dominic.

The habit worn by the Fathers and Brothers consists of a white tunic; a scapular, which is a long, narrow piece of white cloth the width of the shoulders, hanging down from the shoulders in front and back; a "capuce" or white hood with a short cape attached; a belt and a Rosary. When preaching, the Fathers sometimes wear a black "cappa" and hood, which prompted the English to call them "Blackfriars". The scapular and Rosary were given to the order by the Blessed Mother herself, and are looked upon by the Fathers and Brothers as a uniform of a soldier in her service.
