Istanbul's Bosphorus strait flows between the Black and Marmara seas connecting Georgia to Greece and the Sea of Azov with the Aegean. Docked nearby the Dolmabache palace enormously extravagant cruise liners pour travellers into the city for a fast paced one day race through history. Container ships loaded high with commerce churn through its currents as ferries move the local population to their work. Both its European and Asian shores are lined with palaces and houses of breathtaking size and incredible wealth and style. These waters that link three continents - Europe, Asia and Africa - are clean and appear calm, yet below the surface dangerous currents flow in opposing directions making it difficult to navigate at its narrowest points and impossible to swim or dive in. On these shores at Chalcedon, in 451 AD, the Fourth Ecumenical Council was held to defend the human and divine natures of Jesus (united, inconvertible and inseparable at his incarnation) against heretical undercurrents. Does it matter that Jesus is fully God and fully Man? If God only Jesus could not represent us in our humanity and if Man only he could not redeem us from our iniquity. The Bosphorus reminds me of the countless unseen currents that threaten our integrity and theology. In the matter of integrity the person we reveal to others might mask a conflicting reality beneath the surface of our soul. In the matter of theology Christian beliefs might be suddenly shaken by trends and teaching designed to work against us moving in the direction of Biblical hope and holiness. Just as Jesus' two true natures were united in Himself, we need our public and private morality joined together by a transforming 'belief that behaves' theology. 'Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.' (1 Timothy 4:18)
