1st Corinthians 8:9

6 yet to us [is] one God, the Father, of whom [are] the all things, and we to Him; and one Lord, Jesus Christ, through whom [are] the all things, and we through Him;

7 but not in all men [is] the knowledge, and certain with conscience of the idol, till now, as a thing sacrificed to an idol do eat [it], and their conscience, being weak, is defiled.

8 But victuals do not commend us to God, for neither if we may eat are we in advance; nor if we may not eat, are we behind;

9 but see, lest this privilege of yours may become a stumbling-block to the infirm,

10 for if any one may see thee that hast knowledge in an idol`s temple reclining at meat -- shall not his conscience -- he being infirm -- be emboldened to eat the things sacrificed to idols,

11 and the brother who is infirm shall perish by thy knowledge, because of whom Christ died?

12 and thus sinning in regard to the brethren, and smiting their weak conscience -- in regard to Christ ye sin;
