What is called Christian, but should rather be termed theological, morality, was not the work of Christ or the Apostles, but is of much later origin, having been gradually built up by the Catholic church of the first five centuries, and though not implicitly adopted by moderns and Protestants, has been much less modified by them than might have been expected. For the most part, indeed, they have contented themselves with cutting off the additions which had been made to it in the middle ages, each sect supplying the place by fresh additions, adapted to its own character and tendencies.
