Agreed, but that doesn’t conflict with any of the principles listed. Works are important, but you obviously can’t earn your way into heaven through works.
I’m a Calvinist, but I think Catholics could also agree with all of these points. I think you’d start to find disagreement in some “emergent” churches (and is part of the reason I have a problem with these churches), and more serious disagreement in the old mainline denominations.
My first post was due to what I perceived as an agenda on the part of the poll takers.
Perhaps C.S. Lewis (Mere Christianity) would be best positioned to devise an objective poll as to how many actually hold Christian beliefs.
