1 Now as touching things offered unto idols, we
      know that we all have knowledge. Knowledge
      puffeth up, but charity edifieth.
       2 And if any man think that he knoweth any
      thing, he knoweth nothing yet as he ought to
      know.
       3 But if any man love God, the same is known of
      him.
       4 As concerning therefore the eating of those
      things that are offered in sacrifice unto idols,
      we know that an idol is nothing in the world, and
      that there is none other God but one.
       5 For though there be that are called gods,
      whether in heaven or in earth, (as there be gods
      many, and lords many,)
       6 But to us there is but one God, the Father, of
      whom are all things, and we in him; and one Lord
      Jesus Christ, by whom are all things, and we by
      him.
       7 Howbeit there is not in every man that
      knowledge: for some with conscience of the idol
      unto this hour eat it as a thing offered unto an
      idol; and their conscience being weak is defiled.
       8 But meat commendeth us not to God: for
      neither, if we eat, are we the better; neither,
      if we eat not, are we the worse.
       9 But take heed lest by any means this liberty
      of yours become a stumblingblock to them that are
      weak.
      10 For if any man see thee which hast knowledge
      sit at meat in the idol's temple, shall not the
      conscience of him which is weak be emboldened to
      eat those things which are offered to idols;
      11 And through thy knowledge shall the weak
      brother perish, for whom Christ died?
      12 But when ye sin so against the brethren, and
      wound their weak conscience, ye sin against
      Christ.
      13 Wherefore, if meat make my brother to offend,
      I will eat no flesh while the world standeth,
      lest I make my brother to offend.
