Luckily, you are not in this alone; many people will be involved in your wedding preparations, ceremony, and reception. In theory, according to Jewish law, all that is required for a wedding are a bride, a groom, and two witnesses. In practice, though, there are many roles to be filled in a Jewish wedding. Relatives, friends, and your religious leader all play important parts. Your wedding team will help you make your experience less stressful, more meaningful, and very memorable.
