Two
Number of the God-Son (the Verb) within Trinity, in the Christian symbolic.
If 1 is the essence, 2 is the existence.
The 2 is the first number to be deviated from the unit, said Hugues of Saint Victor, and because of that it symbolizes the sin. It is also the first number which admits the division, symbolizing the corruptible things.
Symbol of sexuality since 2 represents also the division of the unit in male and female.
