I reviewed this book, and they definitely cut out at least one spell that was way worse than this one, and changed some others for the better. I don't have my review notes anymore, so maybe it slipped by, or maybe they ignored my complaints. Often they will just cut something if I savage it too harshly. From memory, this spell (and a number of others) was in the original Unearthed Arcana for 1E, so I guess they were looking for the Nostalga Factor. But yeah, good call on the 4e Ritual thing. Totally no use for this as a spell - any table that really want a wedding ritual "blessed by the gods" can make something up as appropriate, they don't need it spelled out in the PHB.
