The causa of Servant of God, Dorothy Day (1897-1980) occasions many questions for ecclesiastical leadership, some of them canonical. I can suggest three: Day’s abortion, her alleged status as a Communist, and her apparent conflicts with New York’s Cardinal Spellman over the title of her newspaper, The Catholic Worker.
Abortion. Day’s abortion is not a canonical objection to her elevation, as the killing occurred nearly a decade before her 1927 conversion to Catholicism (from Episcopalianism), that is, before Day was bound by 1917 CIC 2350 with its penalty of excommunication. Thus, Day’s repentance for the deed (which she clearly expressed many times) and Confession of the sin (likely offered in her first Confession, celebrated the day after her reception into the Church) would have adequately addressed this tragedy as far as canon law is concerned.
