When the chaff had been so relentlessly severed from the wheat by the persecutions of that age, a moral earnestness and a power of denying the world and self must have been developed, sustained by the divine power of the gospel and furthered by a strict and rigorous application of church discipline to the Christian life, such as the world had never seen before. What most excited and deserved wonder in the sphere of heathendom, hitherto accustomed only to the reign of selfishness, was the brotherly love of the Christians, their systematic care of the poor and sick, the widespread hospitality, the sanctity of marriage, the delight in martyrdom, etc. Marriages with Jews, heathens and heretics were disapproved, frequently even the celebration of a second marriage after the death of the first wife was disallowed. Public amusements, dances, and theatres were avoided by Christians as _Pompa diaboli_. They thought of the Christian life, in accordance with Eph. vi. 10 ff., as _Militia Christi_. But even in the Post-Apostolic Age we come upon indications of a tendency to turn from the evangelical spirituality, freedom and simplicity of the Apostolic Age toward a pseudo-catholic externalism and legalism in the fundamental views taken of ethical problems, and at the same time and in the same way in the departments of the church constitution (§ 34), worship (§ 36) and exposition of doctrine (§ 30, 2). The teachers of the church do still indeed maintain the necessity of a disposition corresponding to the outward works, but by an over-estimation of these they already prepare the way for the doctrine of merit and the _opus operatum_, _i.e._ the meritoriousness of works in themselves. Even the _Epistle of Barnabas_ and the _Didache_ reckon almsgiving as an atonement for sins. Still more conspicuously is this tendency exhibited by _Cyprian_ (_De Opere et eleemosynis_) and even in the _Shepherd of Hermas_ (§ 30, 4) we find the beginnings of the later distinction, based upon 1 Cor. vii. 25, 26; Matt. xxv. 21, and Luke xviii. 10, between the divine commands, _Mandata_ or _Præcepta_, which are binding upon all Christians, and the evangelical counsels, _Consilia evangelica_, the non-performance of which is no sin, but the doing of which secures a claim to merit and more full divine approval. Among the Alexandrian theologians, too, under the influence of the Greek philosophy a very similar idea was developed in the distinction between higher and lower morality, after the former of which the Christian sage (ὁ γνωστικός) is required to shine, while the ordinary Christian may rest satisfied with the latter. On such a basis a special order of Ascetics very early made its appearance in the churches. Those who went the length of renouncing the world and going out into the wilderness were called Anchorets. This order first assumed considerable dimensions in the 4th century (§ 44).
