In like manner every calling or office has its own type, which those who fill it are bound to maintain; and to deviate from the type in any material point is to relinquish the calling. Thus both Chaucer and Goldsmith have drawn pictures of a true parish priest; these differ in details, but on the whole they agree together, and are one in such sense, that sensuality, or ambition, must be considered a forfeiture of that high title. Those magistrates, again, are called "corrupt," who are guided in their judgments by love of lucre or respect of persons, for the administration of justice is their essential function. Thus collegiate or monastic bodies lose their claim to their endowments or their buildings, as being relaxed and degenerate, if they neglect their statutes or their Rule. Thus, too, in political history, a mayor of the palace, such as he became in the person of Pepin, was no faithful development of the office he filled, as originally intended and established. 3. In like manner, it has been argued by a late writer, whether fairly or not does not interfere with the illustration, that the miraculous vision and dream of the Labarum could not have really taken place, as reported by Eusebius, because it is counter to the original type of Christianity. "For the first time," he says, on occasion of Constantine's introduction of the standard into his armies, "the meek and peaceful Jesus became a God of battle, and the Cross, the holy sign of Christian Redemption, a banner of bloody strife. . . . . This was the first advance to the military Christianity of the middle ages, a modification of the pure religion of the Gospel, if directly opposed to its genuine principles, still apparently indispensable to the social progress of men."[173:1] On the other hand, a popular leader may go through a variety of professions, he may court parties and break with them, he may contradict himself in words, and undo his own measures, yet there may be a steady fulfilment of certain objects, or adherence to certain plain doctrines, which gives a unity to his career, and impresses on beholders an image of directness and large consistency which shows a fidelity to his type from first to last. 4.
