Pari passu with this logical, communistic Chiliasm we can trace the development of an illogical, individualistic Chiliasm in St. Paul, Clement of Rome and Hermas. It is already manifest even at this early stage, that the weight of influence and power of control in the Christian societies is on the side of the individualists. This is due to two causes. In the first place the communists among the Christians worked under a great handicap. The underlying economic institutions of society can indeed be changed. But they can be changed--on any considerable scale--only very slowly and by enormous effort. At any attempt to change them a thousand interested and determined antagonists at once arise. It is not too much to say that had all Christians insisted upon communism as an essential element of the Christian faith and practice, Christianity in the Roman world could never have developed into anything more than an unimportant sect. The very fact that Christianity spread as rapidly as it did in the first century of its existence is proof that the communists in the Church made very little headway. It was hard enough to combat pagan religion and philosophy. Had the property institutions been attacked also, the primary religious objects would have been lost sight of in the conflict. In the second place the more practical minded Christian leaders would be antagonistic to a doctrine and practice which alienated many persons who might otherwise be won to the Church, and practically minded persons outside the Church regarded the individualists with more favor and were more easily influenced by them to become Christians themselves. The early importance attained by the Church of Rome is to be largely ascribed to the predominance in its councils of such practical persons.[39] Communism had no hold there at all and Chiliasm was never allowed to interfere with the practical workings of society. By the time of Justin the three concepts; Chiliasm, Communism, and Individualism had arrived at a modus vivendi. According to this arrangement Chiliasm and Communism held sway as theories while individualism ruled in the world of fact. This agreement proved very satisfactory and for more than half a century was the accepted thing. It is seen in full force in Tertullian.
