A system of numerology called Gematria was used by the Jews which gives a numerical value to a word or even a phrase. The reason for having Gematria was that a numerical equivalence could not be coincidental. Since the world was created through God’s “speech,” each letter represents a different creative force. Thus, the numerical equivalence of two words reveals an internal connection between the creative potentials of each one. Gematria was also used among the Greeks and was in common use at the time of the writing of the New Testament.
One name in the New Testament is of course Mary Magdalene and the Greek Gematria of her title “H Magdalhnh” adds up to 153. The number 153 is very important as it is a symbolic number in the canon of the Greek geometers most particularly it is a numerical abbreviation for the "vesica piscis".
The Vesica Piscis, which the Greeks and Pythagoras referred to as "The Matrix" and "Doorway to Life", is when two circles are drawn together so that the edge of one passes through the center of the other. Its also significant that circles are used to create the Vesica Piscis as any circle that has a diameter of 7 units will have a circumference of 22 units. Those two numbers also have a connection with Mary Magdalene as her feast day is on the 22/07 (July).
So with that in mind, let's look at the calculation for the area of the circle with the “7” radius. The formula is “pi” (22/7) times the square of the radius (7 x 7 = 49). 22/7 x 49 is 154. If you use the alternative decimal version of “pi” (3.14) the result 153.86, the Vesica Piscis and the Magdalene.
