On November 20, 2009, Charles Colson, Robert George, and Timothy George set forth a document they called The Manhattan Declaration affirming the sanctity of life, marriage, and religious liberty and calling on Christians everywhere to sign it. Since then, hundreds of thousands of people who profess faith in Christ have affixed their signatures to the document.

However, significant debate remains over the fact that the Manhattan Declaration has garnered the signatures of a number of leaders from Evangelical, Anglican, Roman Catholic and Eastern Orthodox traditions. Many prominent evangelical leaders are concerned about the accuracy and propriety of identifying such theologically disparate groups as "Christian" together in the same document.

Evangelical leader R.C. Sproul, who elected not to sign the Manhattan Declaration, sums up the controversy by his response (posted 12/8/09) on his blog, "The Manhattan Declaration confuses common grace and special grace by combining them. While I would march with the bishop of Rome and an Orthodox prelate to resist the slaughter of innocents in the womb, I could never ground that co-belligerency on the assumption that we share a common faith and a unified understanding of the gospel."
