Actually God is the only source of truth. Code can strives to mimic that truth. But there's one source of absolute truth.
Discussion
God is truth. He is the fundemental eternal reality, Everything else that is is a derivative of his essential existence. Anything that is true, is true because it cooresponds to his nature.
And what is "God"?
Everything.
That means truth is everywhere including in code.
It is up to the will and the eye of the beholder to discern and distill the truth found everywhere.
