St Joseph, guardian of the infant Jesus, is honoured as patron of the Universal Church. He is depicted as such in this statue in the Church of the Immaculate Conception on Farm Street in London. His feast is 19 March.
Josephology is the theological study of Saint Joseph, the husband of the Blessed Virgin Mary. Records of devotions to Saint Joseph go back to the year 800 and Doctors of the Church since Saint Thomas Aquinas have written on the subject.
