One Tree Hill, Season 3

Nathan:
Father, can I ask you a question? When you decided you wanted to be a priest how did you know it was the right thing to do?

Priest:
I had a devout believe in God.

Nathan:
Can you prove that to us, with some sort of a test I mean?

Priest:
Of course not.

Nathan:
Just like you can't prove love with a test. I mean, this is just a score on a sheet of paper. Sure, Haley and I have our differences, but this test doesn't show how hard we’ve worked to keep this relationship together, or that I can’t stand it when we're apart, or that every time I look at her I know that I'm gonna be with her for the rest of my life. We love each other father, no test is going to show that.
