Discussing the chances of the present struggle for the survival; of the Church in that very civilization which she created and which is now generally abandoning her.
The five the main forms of attack
These five are, in their historical order, 1. The Arian; 2. The Mohammedan; 3. The Albigensian; 4. The Protestant; 5. One to which no specific name has as yet been attached, but we shall call for the sake of convenience "the Modern.''
The Arian heresy (filling the fourth, and active throughout the fifth, century), proposed to go to the very root of the Church's authority by attacking the full Divinity of her Founder.
The Mohammedan attack was of a different kind. It came geographically from just outside the area of Christendom; it appeared, almost from the outset, as a foreign enemy; yet it was not, strictly speaking, a new religion attacking the old, it was essentially a heresy; but from the circumstances of its birth it was a heresy alien rather than intimate. It threatened to kill the Christian Church by invasion rather than to undermine it from within.
The Albigensian attack was but the chief of a great number, all of which drew their source from the Manichean conception of a duality in the Universe; the conception that that good and evil are ever struggling as equals, and that Omnipotent Power is neither single nor beneficient.
The Protestant attack differed from the rest especially in this characteristic that its attack did not consist in the promulgation of a new doctrine or of a new authority, that it made no concerted attempt at creating a counter-Church, but had for its principle the denial of unity.
The Modern Attack-The idea of God itself and all that follows on it is man-made and a figment of the imagination.'' This is the attack which has superseded all the older ones, which is now gaining ground so rapidly and whose votaries feel (as did in their hey-day all the votaries of the earlier attacks) an increasing confidence of success.
