text: As Jehovah's Witnesses, we maintain a strict standing on any kind of involvement in false religious practices, traditions, or ceremonies. With such a wedding taking place in one of the false religious churches of Christendom, we would not attend in order to not offend God or allow anyone there to become under the impression that we share in the false religious part of that particular ceremony.\n\n"Been there" doesn't have the slightest idea what they're talking about. Whether a building has windows or not has absolutely nothing to do with it whatsoever. The fact of the matter is that the ceremony will undoubtedly be performed by the church's pastor or priest, and the church itself is steeped in false religious beliefs and practices. True Christians, like her grandmother, would not have any kind of involvement (including attending) in that.
