Romans 14.

But him that is weak in the faith receive not unto decisions1 of reasonings. 2 One person hath faith to eat all things, but he that is weak eateth herbs. 3 Let not him that eateth despise him that eateth not; and let not him that eateth not judge him that eateth; for God hath received him. 4 Who art thou that judgest another's servant? To his own master he standeth or falleth; and stand he shall, for his master is able to make him stand. 5 One [person] judgeth day more than day, another judgeth every day [alike]. Let each be fully assured in his own mind. 6 He that regardeth the day doth regard to [the] Lord, and he that regardeth not the day to [the] Lord doth not regard; and he that eateth eateth to [the] Lord, for he giveth thanks to God, and he that eateth not to [the] Lord eateth not and giveth thanks to God. 7 For none of us liveth to himself and none dieth to himself; 8 for both if we should live, to the Lord we live, and if we die, to the Lord we die; therefore both if we should live and if we should die, we are the Lord's. 9 For unto this [end] Christ died and lived, that he might be Lord both of dead and living. 10 But thou, why judgest thou thy brother? or thou too, why despisest thou thy brother? for we shall all stand before the judgment-seat of God. 11 For it is written, 'I live, saith [the] Lord, that to me shall bow every knee, and every tongue shall confess to God.' 12 So then each of us shall give account concerning himself to God. 13 Let us then no longer judge one another, but judge ye this rather, not to set an occasion of stumbling or offence for one's brother.

14 I know and am persuaded in [the] Lord Jesus that nothing [is] unclean by itself; unless to him that reckoneth anything to be unclean, to him [it is] unclean. 15 For if on account of meat thy brother is grieved, thou art no longer walking in love. Do not with thy meat destroy him for whom Christ died. 16 Let not then your good be ill spoken of; 17 for the kingdom of God is not eating and drinking, but righteousness and peace and joy in [the] Holy Ghost; 18 for he that in this serveth Christ [is] acceptable to God and approved by men. 19 So then let us pursue the things of peace and the things of edifying one another. 20 Do not for the sake of meat pull down the work of God. All things are clean; but [it is] evil to the man that eateth while stumbling. 21 [It is] right not to eat flesh nor drink wine nor anything in which thy brother stumbleth [or is offended or is weak]. 22 Hast thou faith? to thyself have [it] before God. Happy [is] he that judgeth not himself in what he approveth; 23 but he that doubteth is condemned if he eat, because [it is] not of faith; but everything which [is] not of faith is sin.
