   While the Jews taught that "he who transgresses all the
   precepts of the law has broken the yoke, dissolved the
   covenant, and exposed the law to contempt; and so has he done
   who has only broken one precept;" they also taught, "that he
   who observed any principal command was equal to him who kept
   the whole law," and gave for an example the forsaking of
   idolatry.  To correct this false doctrine was the object James
   had in view.
