Today, in the 1962 Dominican Rite Calendar, we celebrate the feast of the illustrious St. Catherine of Siena, Virgin, Doctor of the Church, Patroness of the Third Order of St. Dominic. At the time the 1962 Dominican Breviary was published, her feast was II Class, though it could be celebrated as I Class by Tertiaries and Churches which bore her name. By the time of the publication of the English translations of the Breviarium S.O.P., the Order raised her feast to I Class. Accordingly, the festive office is prayed according to the rubrics.
As today is Saturday, we will pray 2nd Vespers of her feast this evening, and make a commemoration of the Feast of St. Joseph the Worker.
