Our Apostolic Mandate requires from Us that We watch over the purity of the Faith and the integrity of Catholic discipline. It requires from Us that We protect the faithful from evil and error; especially so when evil and error are presented in dynamic language which, concealing vague notions and ambiguous expressions with emotional and high-sounding words, is likely to set ablaze the hearts of men in pursuit of ideals which, whilst attractive, are nonetheless nefarious.
Pope Pius XI accept with sincere belief the doctrine of faith as handed down to us from the Apostles by the orthodox Fathers, always in the same sense and with the same interpretation.
Pope Pius XOnce for all beloved children, the surest, easiest, shortest way is by the Eucharist. It is so easy to approach the holy table, and there we taste the joys of Paradise
