Romans 14:22-23
(22) Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth.
(23) And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
Concerning personal convictions in areas where different views exist, Paul concluded, So whatever you believe about these things (lit., “The faith that you have,” or “Do you have faith?”) keep between yourself and God. A Christian must not insist on influencing a believer with tighter scruples to change his ways. It should be something “in his own mind” (v. 5), for he lives “to the Lord” (v. 8). Paul considered a Christian like himself who had a clear conscience on such matters blessed (lit., “happy”). On the other hand, a Christian who has doubts is condemned (perf. pass. verb, “stands condemned”) if he eats. If a Christian eats food or does anything when he has doubts in his own mind as to whether it is right or wrong before God (one who is “weak” in faith, vv. 1-2), his action does not spring from (ek, “out of”) his faith or trust in God and is therefore wrong. As Paul generalized, Everything that does not come from (ek, “out of”) faith is sin. The principle is, “When in doubt, don’t.” The “strong” Christian (15:1) is wrong if he causes a weak brother to sin (by doing something while doubting, 14:20), and a weak brother (vv. 1-2) who goes against what he doubts also sins (v. 23).
