The Greek conjunction dioper (from dia + per) means 'for this very reason' or 'therefore' — a strong inferential particle drawing a firm logical conclusion from what has been established.
Dioper is Paul's word for the necessary consequence. In 1 Corinthians 8:13, after establishing that love must govern the exercise of Christian freedom, Paul uses dioper to draw the inevitable personal conclusion: 'therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again.' This word captures the movement from theological principle to practical surrender — the logic of love. It models how biblical reasoning should work: doctrine leads to devotion, truth leads to transformed behavior.
