Kehillah in Rome 14:22-23

Orthodox Jewish Bible

²² The emunah that you have, keep beshita (as a matter of conviction or principle) to yourself before G-d. Ashrey is the man who does not condemn himself by the things he approves.

²³ But in the man who doubts, there is found in him a dvar ashmah (a thing of guilt, condemnation) if he eats, because it is not of emunah. And whatever is not of emunah is averah (sin).
