Neque enim mystica Christi Sponsa, saeculorum decursu, contaminata est unquam, neo contaminari aliquando potest, teste Cypriano: « Adulterari non potest Sponsa Christi: incorrupta est et pudica. Unam domum novit, unius cubiculi sanctitatem casto pudore custodit ». - Mortalium Animos (Pius XI)
During the lapse of centuries, the mystical Spouse of Christ has never been contaminated, nor can she ever in the future be contaminated, as Cyprian bears witness: "The Bride of Christ cannot be made false to her Spouse: she is incorrupt and modest. She knows but one dwelling, she guards the sanctity of the nuptial chamber chastely and modestly." - Mortalium Animos (Pius XI)
