The Second Mile Was Illegal
The 'go the second mile' command referenced a specific Roman law that made the first mile compulsory.
Matthew 5:41 — 'And whosoever shall compel thee to go a mile, go with him twain.' The Greek verb angareuō means to press into service, specifically from the Persian royal post system (angareia) adopted by Rome. A Roman soldier could legally compel a civilian to carry his pack for one Roman mile (approximately 1,480 meters). It was a humiliation embedded in law. The second mile had no legal basis: it was not required and was entirely the civilian's choice. By going the second mile voluntarily, the person who had been compelled was now acting on their own terms. The instruction reframes the relationship: the first mile is endured; the second is chosen. This is a Roman-legal observation, not a theological one.

Evidence Notes
Roman angareia practice is documented in ancient sources. The Greek angareuō appears in Matthew 5:41 and 27:32 (Simon of Cyrene compelled).
