The passage read at most weddings was not written for weddings. Paul was writing to a divided church about how to treat people who were difficult, which arguably makes it more useful the tenth year than the first.
Featured Scripture
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; Rejoiceth not in iniquity, but rejoiceth in the truth; Beareth all things, believeth all things, hopeth all things, endureth all things.
1 Corinthians 13:4–7KJV
