The song “Ave Maria” is a popular choice for Catholic weddings, and it is liturgically appropriate to include it, if the couple chooses to do so. (In fact, it was a part of my own wedding Mass.) When the bride and/or groom has a close relationship to Mary, the song can be a special way to honor that. And because the vocation of marriage often includes raising children, it’s nice to have a song that acknowledges and honors the mother of Christ, who understands that experience intimately.
