What is the reasoning/policy behind the practice that a JW can't attend an event such as funeral or wedding in another church? I know of someone that didn't attend her older sisters funeral because it was held in a Baptist church. She waited outside until the service was over and then went to the family dinner afterwards. Now, my cousin may not attend her brother's wedding because it will be in a Catholic church--and you know the Catholic's are the JW's arch enemy.
I was just wondering if there is something in writing somewhere that puts forth this policy to the JW's. It's ridiculous to me.
