God requires a faithful fulfillment of the merest trifle given us to do, rather than the most ardent aspiration to things to which we are not called.
Saint Francis de SalesMany great persons have been of opinion that love is no other thing than complacency itself, in which they have had much appearance of reason. For not only does the movement of love take its origin from the complacency which the heart feels at the first approach of good, and find its end in a second complacency which returns to the heart by union with the thing beloved--but further, it depends for its preservation on this complacency, and can only subsist through it as through its mother and nurse; so that as soon as the complacency ceases, love ceases.
Saint Francis de SalesMarital intercourse is certainly holy, lawful and praiseworthy in itself and profitable to society, yet in certain circumstances it can prove dangerous, as when through excess the soul is made sick with venial sin, or through the violation and perversion of its primary end, killed by mortal sin; such perversion, detestable in proportion to its departure from the true order, being always mortal sin, for it is never lawful to exclude the primary end of marriage which is the procreation of children.
