If accordingly a clergy is to be trained up likely to supply the intellectual cravings of the present day, they must be placed on a level with its ripest knowledge, and be acquainted with the nature and origin of the forms of doubt which they will encounter. The church has indeed a large field, where work and not thought is to be the engine which the clergy must use in their labours; truly a home mission, where men and women for whom Christ died, require to be lifted out of their mere animalism, and taught the simplest truths of Christ, and prayer, and immortality: and noble are the efforts that Christians have made, and are making, for an object so religious and philanthropic; but there is a danger lest this very energy of work, which accords so naturally with the utilitarianism of the English character, should lead us to forget that there is an opposite stratum of society, to which also Christianity has its message, which is only to be reached by the delicate gifts of intellect and by the ripest learning. If Christianity is to be presented to this class, adapted to the demands of the age so far as they are reasonable, but unmutilated and unaltered in its body of revealed doctrine, preserving in its integrity the faith delivered to the saints; so that apostles might recognize it as being that which they themselves taught, and for which they laid down their lives; it is necessary that Christian students should be trained specially for the work, by a learned and intelligent appreciation of truth, such as will create orthodoxy without bigotry, and charity without latitude. If we have to dread their going forth with hesitating opinions, teaching, through their very silence concerning the mysterious realities which constitute the very essence of Christianity, another gospel than that which was once for all miraculously revealed; there is almost equal ground for alarm if they go forth, able only to repeat the shibboleths of a professional creed, and unable to give a reason of the glorious hope that is in them. In the former case they will fail to teach historic and dogmatic Christianity, because they do not believe it; in the latter because they do not understand its meaning and evidence. If they need piety as the first requisite, they need knowledge as the second. In certain conditions of the church, study is second only to prayer itself as an instrument for the Christian evangelist. It is hoped, therefore, that a sketch of a department not previously treated as a whole, may indirectly be an aid to the Christian faith, if it shall perform the humble office of supplying some elements of instruction to the Christian student.
