These peculiarities also, and the secrecy with which their worship was necessarily conducted because it was not allowed, had led to calumnies concerning them, imputing the grossest immorality as well as cruelty. The apologies of Quadratus, Aristides, and Justin, were probably the first connected revelation of the Christian doctrines which the emperor could have; but these would be very far from conveying to him the character of the Church as an institution. They were intended to obviate the persecutions arising from the causes above described, to show the purity of Christian morality, the reasonableness of Christian belief, the fidelity of Christian sentiment to the imperial rule as established by a divine providence. They were not in the least intended to lay before him the Christian Church as a whole. Thus Justin, replying to the accusation that they were expecting a kingdom, says, “You rashly conceive that we mean a human one, whereas we speak of that with God.” We may then, it seems, conclude with certainty that Antoninus was only partially aware of what Christianity was. That discipline of the secret, which was itself the result of persecution—of the Christian Faith having to make itself a place in a world utterly opposed to it,—became at once its protection, and the cause of further persecution; of persecution, in so far as it put Christians under general suspicion, but of protection, inasmuch as it covered with a veil that complete moral revolution to which the Christian Faith was tending from the first, and towards which it was continually advancing. Could Trajan have foreseen what was apparent under Constantine, his treatment of Christians would have had no forbearance or hesitation in it, his blows no intermission or doubtfulness. As it is, up to the time we are now considering, there are no traces of a general persecution against the Christian name organised by the emperor as head of the State. There are numberless local and individual persecutions starting up in this city and in that, and arising from the fundamental contrariety of Christian belief to the existing heathen worship and the ordinary heathen life. Such we have and no more. And so a great host of martyrs in single combat won their crown. But the emperor did not set himself to destroy a unity which he did not see.
