Conclusion.

The appearance of Christ on earth and the spreading of historical Christianity roused against itself the mobilization of all the forces of Hades. In answer to this, Christianity presented to the world its defense. It answered persecutions with professions of faith and martyrdom; it answered heresies, schisms and false doctrines with Ecumenical Councils, the doctrines of the Holy Fathers and dogmas. It answers the continual torrent of nagging criticism with impartial apologetics, it answers slander with holiness, and it answers the efforts of all the power of Hades with the Holy Church.
