There are not any required "Bible wordings for the wedding cards." If you would like to include a Bible passage on your wedding card, you are free to choose any verses you would like. One passage that is used often in weddings is 1 Corinthians 13. I have seen verses from 1 Corinthians 13 also on wedding invitations.
