Pope Pius XIIChristian mothers, if only you knew the future of distress and peril, of shame ill-restrained, that you prepare for your sons and daughters in imprudently accustoming them to live hardly clothed and in making them lose the sense of modesty, you should be ashamed of yourselves and of the harm done the little ones whom heaven entrusted to your care, to be reared in Christian dignity and culture.
Pope Pius XIIThis practice of adoration is based on strong and solid reasons. For the Eucharist is at once a sacrifice and a sacrament; but it differs from the other sacraments in that it not only produces grace, but contains in a permanent manner the Author of Grace Himself. When, therefore, the Church bids us to adore Christ hidden behind the Eucharistic veils and to pray to Him for spiritual and temporal favors, of which we ever stand in need, she manifests faith in her divine Spouse who is present beneath these veils, she professes her gratitude to Him, and she enjoys the intimacy of His friendship
