In 325 AD, following the First Council of Nicaea, departures from the beliefs of the state church were classified as civil violations within the Roman Empire. Numerology had not found favor with the Christian authority of the day and was assigned to the field of unapproved beliefs along with astrology and other forms of divination and "magic". Despite this religious purging, the spiritual significance assigned to the heretofore "sacred" numbers had not disappeared; several numbers, such as the "Jesus number" have been commented and analyzed by Dorotheus of Gaza and numerology still is used at least in conservative Greek Orthodox circles. However, despite the church's resistance to numerology, there have been arguments made for the presence of numerology in the Bible and religious architecture. For example, the numbers 3 and 7 hold strong spiritual meaning in the Bible. The most obvious example would be the creation of the world in 7 days. Jesus asked God 3 times if he could avoid crucifixion and was crucified at 3 in the afternoon. 7 is the length of famine and other God-imposed events and is sometimes followed by the number 8 as a symbol of change.
