Does your order have Tertiaries: similar to what Benedictines might call "Oblates", and Franciscans might call their "Third Order"?
The Dominican Order consists of friars (who may be either non-ordained cooperator brothers or priests), nuns (cloistered), sisters (active or apostolic), and lay Dominicans. All are part of the worldwide Order of Preachers, and share in the preaching mission of the order, each according to the particular vocation in question, i.e., lay Dominican, sister, priest, etc. "Lay Dominicans" or "Dominican Laity" are the terms used today to refer to the Third Order of St. Dominic. Lay Dominicans live in the world and may be married or single; and they choose to grow into the fullness of their baptismal calling in the lay state, but as Dominicans and with a distinctly Dominican spirituality. Examples of famous lay Dominicans include St. Catherine of Siena, St. Rose of Lima, and Blessed Pier Giorgio Frassati (pictured).
