My parents (both Catholics) renewed their vows for their 25th anniversary. The ceremony was essentially the same as a wedding Mass. They were given a booklet with 3-4 different options for each of the readings. They were also told that they didn't have to use any of the options, as long as they followed the pattern of first reading from the Old Testament, second reading from the New Testament, Gospel reading from the Gospels.
1st Corinthians 13 is one of the options. Another option is the reading that goes "you who are wives, be submissive to your husbands." (
