I just plain have to quote this and add emphasis:
Marriage is more than the wedding ceremony, the flowers, the dress and the photos, Pope Francis said in his weekly general audience: It is a participation in the Church’s mission.
“Men and women, courageous enough to carry this treasure in the ‘earthen vessels’ of our humanity … are an essential resource for the Church, as well as for the whole world!”
Speaking to the crowds gathered in St. Peter’s Square for his weekly catechesis on May 6, the Pope explained that each marriage that demonstrates the beauty of the sacrament enriches the life of the Church. In the same way, it “is impoverished when marriage is disfigured in any way.”
