Basically, Gematria is searching for different patterns through the text, such as the amount of words beginning with a vowel. If the amount of these matches is divisible by a certain number, such as 7 (which is said to be God's number), there is an incontestable argument that the Spirit of God is ever present in the text. Another important aspect in gematria are the numerical values of letters: A=1, B=2 ... I=9, J=10, K=20 and so on. The Gematriculator uses Finnish alphabet, in which Y is a vowel.Of course they would use the Finnish alphabet. Doesn't everyone?
Note: Harriet Miers turns up in the word list thus:
harriet 7 7 7=7
miers 14 14=7x2
So I'm thinking that should please these folks.
