Romans 12:3-5 NIV

3 For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the faith God has distributed to each of you. 4 For just as each of us has one body with many members, and these members do not all have the same function, 5 so in Christ we, though many, form one body, and each member belongs to all the others.

1 Corinthians 10:14-17 NIV

14 Therefore, my dear friends, flee from idolatry. 15 I speak to sensible people; judge for yourselves what I say. 16 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? 17 Because there is one loaf, we, who are many, are one body, for we all share the one loaf.
