There is more to numerology than meets the eye. The Wikipedia section on this subject is limited in scope and understanding, but a good place to get a somewhat objective perspective.

Pythagoras and other philosophers of the time believed that because mathematical concepts were more "practical" (easier to regulate and classify) than physical ones, they had greater actuality. St. Augustine of Hippo (A.D. 354–430), wrote "Numbers are the Universal language offered by the deity to humans as confirmation of the truth." Similar to Pythagoras, he too believed that everything had numerical relationships and it was up to the mind to seek and investigate the secrets of these relationships or have them revealed by divine grace.
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.
Some alchemical theories were closely related to numerology. For example, Persian alchemist Jabir ibn Hayyan framed his experiments in an elaborate numerology based on the names of substances in the Arabic language.
Numerology is prominent in Sir Thomas Browne's 1658 literary Discourse The Garden of Cyrus. Throughout its pages the author attempts to demonstrate that the number five and the related Quincunx pattern can be found throughout the arts, in design, and in nature – particularly botany.
Numerology is a popular plot device in fiction. Sometimes it is a casual element used for comic effect, such as in an episode titled "The Séance" of the 1950s TV sitcom I Love Lucy, where Lucy dabbles in numerology. Sometimes it is a central motif of the storyline, such as the movie π, in which the protagonist meets a numerologist searching for hidden numerical patterns in the Torah; the TV show Touch which focuses almost entirely on the role of numerology in the events and coincidences of any person's life; and the movie The Number 23, based on claimed mysteries of the number 23 (itself based on the Law of Fives).
