Romans 14:2

2. For one believeth. This was the case with the Gentiles in general, who had none of the scruples of the Jew about the propriety of eating certain kinds of meat. Many of the converts who had been Jews might also have had the same view--as the apostle Paul evidently had--while the great mass of Jewish converts might have cherished these scruples. May eat all things. That is, he will not be restrained by any scruples about the lawfulness of certain meats, etc. Another, who is weak. There is reference here, doubtless, to the Jewish convert. The apostle admits that he was weak, i.e., not fully established in the views of Christian liberty.
