If our country being founded upon a majority of Christian Values,
Before you answer that, you'd have to define what, exactly, you meant by "Christian Values."
For example, the 10 commandments are part of the Hebrew Bible, so calling them "Christian Values" seems a little antisemitic to me: they're Jewish values if anything.
I mean, when someone says "Christian values," that sort of seems to imply (at least to me) that they're Christian as opposed to Buddhist, or Secular, or whatever. If that is not what one means, then why refer to them as "Christian" values? Why not just say "moral values" or something, if they are universal?
If you do intend to imply that Christian morals are somehow different (let alone better) than non-Christian morals, then you'd have to give specific examples, and then provide the evidence where one or more Founding Fathers addresses this value specifically.
and a good portion of our fore fathers being Christian
You're going to have to provide evidence of that, too. (1) As others have questioned, do you consider branches such as Deists, or UU, or Freemasons, to be Christian? (2) If so, then you might be right. If not, then please provide a list of who you consider to be Founding Fathers, and what their religion was, so that we might verify that more than 50% of them were indeed Christian.
