Dominican Order

The Dominican Order, known formally as the Order of Preachers (Latin: Ordo Praedicatorum, postnominal abbreviation OP), is a mendicant order of the Catholic Church founded in France by the Spanish priest Saint Dominic. It was approved by Pope Innocent III via the Papal bull Religiosam vitamon 22 December 1216. Members of the order, who are referred to as Dominicans, generally carry the letters OP after their names, standing for Ordinis Praedicatorum, meaning of the Order of Preachers. Membership in the order includes friars, nuns, active sisters, and affiliated lay or secular Dominicans (formerly known as tertiaries, though recently there has been a growing number of associates who are unrelated to the tertiaries).

Founded to preach the Gospel and to oppose heresy, the teaching activity of the order and its scholastic organisation placed the Preachers in the forefront of the intellectual life of the Middle Ages. The order is famed for its intellectual tradition, having produced many leading theologians and philosophers. In the year 2018 there were 5,747 Dominican friars, including 4,299 priests. The Dominican Order is headed by the Master of the Order, as of 2019, Gerard Timoner III. Mary Magdalene and Catherine of Alexandria are the co-patronesses of the Order.
