This is why I bring up the Declaration of Independence. A document is not ‘Christian’ because it mentions ‘God’, ‘Christ’, ‘Heaven’, Etc. It is Christian if it is written by ‘Christians’, for ‘Christians’, to the edification of God All Mighty.
The authors of the Declaration of Independence edified God All Mighty?
But since the Constitution wasn't written for Christians but for all citizens, by your logic it is not a Christian document.
