On p. 19, Jeremy Waldron states that: "My book is about the relation in Locke's thought between basic equality and religious doctrine--and that is exactly what the First Treatise is devoted to." Locke is often thought of as an implacable enemy of Christianity, but that was only true of the concept of divine right of kings, as embodied in the works of Robert Filmer. Locke wrote the Reasonableness of Christianity, which supports Christianity, though of course not to the extent of the desires of the orthodox.
On p. 142, Waldron quotes Locke that "[we] are [God's] property, whose Workmanship we are, made to last during his, not another's Pleasure, and that i am not made to last during my own pleasure, so that i do not have moral authority over my own life." On p. 163, Locke continues that "the Idea of a Supreme Being, . . whose Workmanship we are, and on whom we depend . . . the original and foundation of all Law is dependence. A dependent intelligent being is under the power & direction & domination of him on whom he depends . . if man were independent, he could have no law but his own will . . .he would be a god unto himself." These sentences alone radically remove Locke as a supporter of 20th and 21st century thin version of ethical liberalism, which caters to a radical agnostic autonomous individualism. On p. 145, Waldron shows that Locke approved of capital punishment under certain circumstances, another difference from contemporary liberalism.
On p. 187, Waldron quotes Locke as saying that "true and proper relief of the poor . . consists in finding work for them," a sentence more likely to be found in a republican than democratic platform.
Locke is thought of as a kind of 'apostle of toleration,' although he never tolerated atheists, and while his later, more refined thought tolerated Catholicism, in 1667, in his Essay on Toleration, he wrote (p. 222 of Waldron), that "Papists are not to enjoy the benefit of toleration."
All in all, Waldron does an excellent job of showing, perhaps to the dismay of 21st century agnostic secularists, that current enlightenment regimes, such as the USA, are mole hills built on the mountain of centuries of Christian thinking and writing.
