Cambridge Greek Testament Commentary
Romans 14 - Introduction
14. (1) Scruples must not be allowed to separate brethren: (3) they do not separate from GOD: (4) we have no right to judge those who, in their particular choices of action, all own allegiance to the one Lord: (10) judgment is reserved for GOD.
(13) The true Christian way is to avoid all offence to brethren in matters indifferent, and, positively, to concentrate our aim upon the weightier matters.
