You know this is so simple. Follow the law. The Bible commands it. Being that WT claims to follow the Bible there should not be an issue. The Norwegian government is not commanding WT to break any Biblical commandments. In fact the government in question is not commanding anything. It is simply giving the conditions it will grant funds that it controls. The Norwegian government has that right.
