The April 1934 issue of the Acta Apostolicae Sedis records the Holy See's papal acts, canonization proceedings, Roman Congregation decrees, ecclesiastical appointments, honors, publications, and administrative notices. Pope Pius XI's activities include the closing of the Holy Year, the appointment of bishops, and the canonizations of Maria Michaela of the Blessed Sacrament, Louise de Marillac, Joseph Benedict Cottolengo, Pompilius Maria Pirrotti, and Teresa Margaret Redi. The accompanying homilies present their prayer, penance, charity, and service of the poor as models of Christian holiness. The issue also traces the life, ministry, virtues, miracles, and beatification process of Anthony Mary Claret, from his missionary work in Spain and Cuba to his service at the royal court and defense of papal infallibility. A decree condemns Friedrich Schmidtke's Die Einwanderung Israels in Kanaan to the Index of Prohibited Books. Other decisions regulate Byzantine-rite bination and the purification of sacred vessels, while canonical responses address the distribution of prebendal and choral income. Curial appointments, papal orders and honors, a necrology, and notices of Vatican books complete the record.
