If someone said you had to give everything you own and spend all your days serving another person, 24/7, 365 days a year, you would say “No way. That too much: It’s slavery!” But that’s exactly what we promise to do for the one we love when we get married. The old exhortation from Catholic weddings puts it well: “Sacrifice is usually difficult and irksome. Only love can make it easy, and perfect love can make it a joy.”
