The Statement of Faith that I think should describe the fundamentals of Christianity is that which has been used by Christians for 1500+ years. Give me that Old Time Religion!
I refer to, of course, the Nicene Creed:

the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.
We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
