The Formal Argument

Stated more formally, the argument is:

Jesus claimed to be God. His claim is either true or false.

If it is true, then, ipso facto, He is God.

If the claim is false, then:

• He said it knowing it was false, in which case He is a liar, or
• He said it NOT knowing it was false, in which case He was mad (a lunatic)

Therefore, we are left with three logical options: He is either:

• God
• A Liar, or
• A Lunatic
