Acts 9:4
He fell to the ground and heard a voice say to him, 'Saul, Saul, why do you persecute me?'—the doubled name echoes God's address to Abraham and Moses, marking a commission moment. Crucially, Christ identifies himself with the persecuted church; harming believers = harming Jesus. This foundational equation ('you persecute me') becomes the theological lens through which Paul will later develop the doctrine of the church as the body of Christ (1 Cor 12:12-27).
