Not only, in strict truth, was marriage instituted for the propagation of the human race, but also that the lives of husbands and wives might be made better and happier. This comes about in many ways: by their lightening each other's burdens through mutual help; by constant and faithful love; by having all their possessions in common; and by the heavenly grace which flows from the sacrament.

Hence, the devotion which God sends to the succor of His Church and of the nations at the present time is the devotion to the Most Holy Eucharist. It is the highest of all devotions.
Pope Leo XIII
