110 That form of piety, then, should be held in highest esteem by means of which man honors and loves God more and dedicates himself with greater ease and promptness to the divine charity; a form which our Redeemer Himself deigned to propose and commend to Christians and which the Supreme Pontiffs in their turn defended and highly praised in memorable published documents. Consequently, to consider of little worth this signal benefit conferred on the Church by Jesus Christ would be to do something both rash and harmful and also deserving of God's displeasure.
