If your mother is referring to “The Bridal Chorus” from Richard Wagner’s opera Lohengrin, many Catholic parishes recommend that it not be used because it is considered secular music. Ideally, only liturgical music should be used during a Catholic wedding. However, some parishes are more lenient on the issue than others and will allow secular classical music. A prospective couple should check with the wedding coordinator of the parish at which they are to marry to determine local protocol.
