Saint Ursula
The Ursulines, also known as the Order of Saint Ursula (Post-nominals: OSU), is an enclosed religious order of consecrated women that branched off from the Angelines, also known as the Company of Saint Ursula, in 1572. Like the Angelines, they trace their origins to their foundress Saint Angela Merici and place themselves under the patronage of Saint Ursula. While the Ursulines took up a monastic way of life under the Rule of Saint Augustine, the Angelines operate as a secular institute. The largest group within the Ursulines is the Ursulines of the Roman Union.
