<p>14:2 <i>One man has faith to eat all things- </i>The faith was surely faith in Christ's cleansing work by which He had ended the Mosaic law and all conception of clean and unclean food. </p><p><i>But he that is weak eats herbs</i>- Vegetarianism was associated with hyper legalistic Judaism, whereby every kind of meat was feared to be not completely bloodless or <i>kosher</i>. But those who had this position were &quot;weak&quot;. Yet they were not to be argued with but accepted. This is not to say that Paul has no argument about this issue, for he clearly does elsewhere, as did the Lord Himself. But the point was that endless argument of a casuistic nature was not the way to resolve the issue. And again we have a valuable principle there. Presumably Paul does not engage with the Judaistic argument in the same way as he did in Galatians because he has already argued that justification is by grace and not the works of the law, and perhaps that point was accepted in general terms- whereas in Galatia it was not.</p>
