Before you continue reading I would suggest you read my blogs on 'The Torah Its Place in Scripture' and 'The Torah Its Place in our Lives' and especially 'Two Laws or One Torah'.

These decrees were all about 'sacrificial sexual idolatry' causing a loss of salvation, not about food or table manners. Most Christians tend not even take notice or even attempt to unpack Acts 15:21 that gives the reason for these four minimum rulings as discussed in the article 'Two Laws or One Torah?'
