His works cover nearly 40 volumes, often obscure, often tautological, and with no great distinction of style. But their high purpose and philosophical outlook give his writings a permanent place in the history of the thought of his time. The following are the more important works--some of them were rewritten and in a measure recast, and the date given is not necessarily that of the first appearance of the book, but of its more complete and abiding form: _Eustace Conway, or the Brother and Sister_, a novel (1834); _The Kingdom of Christ_ (1842); _Christmas Day and Other Sermons_ (1843); _The Unity of the New Testament_ (1844); _The Epistle to the Hebrews_ (1846); _The Religions of the World_ (1847); _Moral and Metaphysical Philosophy_ (at first an article in the _Encyclopaedia Metropolitana_, 1848); _The Church a Family_ (1850); _The Old Testament_ (1851); _Theological Essays_ (1853); _The Prophets and Kings of the Old Testament_ (1853); _Lectures on Ecclesiastical History_ (1854); _The Doctrine of Sacrifice_ (1854); _The Patriarchs and Lawgivers of the Old Testament_ (1855); _The Epistles of St John_ (1857); _The Commandments as Instruments of National Reformation_ (1866); _On the Gospel of St Luke_ (1868); _The Conscience: Lectures on Casuistry_ (1868); _The Lord's Prayer, a Manual_ (1870). The greater part of these works were first delivered as sermons or lectures.
