Biblical Numerology
In biblical numerology, certain numbers are considered to have specific meanings. For example, the number 3 is often associated with the Holy Trinity (Father, Son, and Holy Spirit), while the number 7 is thought to represent perfection and completion. The number 12 is commonly associated with the 12 tribes of Israel and the 12 disciples, and 40 is often seen as a symbol of testing and trial.
Biblical numerology also associates numbers with specific people, events or periods of time in the Bible. As many are familiar, the number 666 is associated with the Antichrist, the number 144,000 is associated with the number of saved people in the Book of Revelation, and the number 70 is associated with the number of years of the Babylonian captivity.
Biblical numerology has been the center of a great deal of disagreement at least since the First Council of Nicaea in 325 AD, where the Church Fathers repeatedly condemed its use and denounced any system of exclusively numerically-based philsophy.
While they did not subscribe to the mystical adaptations of it, they did yet believe numbers carried significant meaning.
