October 8, 451 - Council of Chalcedon Convenes

As Christianity grew, the early church often settled issues of theology by meeting together in church councils. Many of the councils were held near the Mediterranean Sea for logistical reasons and on October 8, 451 the Council of Chalcedon met to settle the heretical teachings of the Eutychians.  Eutychians did not believe Jesus was both God and man at the same time and met at Chalcedon which is now a city section of Istanbul. This is a picture of the modern-day train station at Chalcedon today called Haydarpasa.
