'It is no coincidence that the ecumenical agenda of the Pope appears in the Manhattan Declaration. This Declaration is as important as the proclamation that launched the 'Evangelicals and Catholics Together' (ECT) movement in 1994.
... the Manhattan Declaration is only the latest step in the downgrade into implementing Catholic social doctrine. There is yet another purpose; one primarily stated in Vatican Council II and post-Vatican Council II documents. Through the use of social issues, the Roman Catholic Church seeks to draw true Evangelical Bible-believers into itself so that there can be no opposition by them on the fundamental issues of the authority of the Bible alone and the Gospel.
In order to soften up the Evangelicals in their separation from the Catholics on biblical doctrinal issues, particularly the authority of the Bible alone and the Gospel, the Catholic modus operandi calls for using social issues on which both Evangelicals and Catholics agree as preliminary common ground...
The Roman Catholic Church's primary goal is to make enforceable its claim that it is the only true church of Jesus Christ and its pope, the claimed 'Vicar of Christ,' has the right to judge everybody, as he did during the Middle Ages.
... the Manhattan Declaration itself must be read in the context of its Website if one is to comprehend what one is about to sign... In recognizing and signing onto MD, Evangelicals are sanctioning the Roman Catholic system and Orthodoxy as 'Christian.' This is something they should have refused to do.' (Richard Bennett).
