A missionary order is a Catholic religious order devoted to active missionary work. No Catholic religious order was founded for that purpose, but all the mendicant orders have been active in this field and others too, in particular the Jesuits, whose members include outstanding missionaries such as Saint Francis Xavier and Matteo Ricci. Even monastic orders have engaged and still engage in missionary endeavours, as did, for instance, the Benedictines whom Pope Gregory the Great sent to evangelize the Angles.
