The Christian Jewish religions have prayers specifically for wedding anniversaries, particularly the Catholic branch of Christianity. The prayers are structured around giving thanks to God for the marriage and its many blessings as well as the strength to endure the struggles that come with the union.
Christian anniversary prayers often times stem from biblical scripture. For example, common prayers come from the book of Matthew, which discusses the act of marriage, as well as the book of Corinthians, which focuses on the many aspects of love. The Catholic Christian prayer focuses on blessings granted from God and strengthening the love of the couple. Lastly, Jewish anniversary prayers are also rooted in scripture, and speak of growing the couple's faith, as well as being positive representatives of Israel and the Israeli people. Many examples of prayers from these religions and more can be found online and in scripture pertaining to a given religion.
