When it began, Christianity was regarded as a system entirely beyond the range and scope of human reason; it was impious to question; it was impious to examine; it was impious to discriminate. On the other hand, it was visibly instinct with the supernatural. Miracles of every order and degree of magnitude were flashing forth incessantly from all its parts.

The moral duty to be expected in different ages is not a unity of standard, or of acts, but a unity of tendency ... At one time the benevolent affections embrace merely the family, soon the circle expanding includes first a class, then a nation, then a coalition of nations, then all humanity and finally, its influence is felt in the dealings of man with the animal world.

Nothing, indeed, could be more unlike the tone of the [Patristic] Fathers, than the cold, passionless, and prudential theology of the eighteenth century; a theology which regarded Christianity as an admirable auxiliary to the police force, and a principle of decorum and of cohesion in society, but which carefully banished from it all enthusiasm, veiled or attenuated all its mysteries, and virtually reduced it to an authoritative system of moral philosophy.

Whenever the clergy were at the elbow of the civil arm, no matter whether they were Catholic or Protestant, persecution was the result.

It had been boldly predicted by some of the early Christians that the conversion of the world would lead to the establishment of perpetual peace. In looking back, with our present experience, we are driven to the melancholy conclusion that, instead of diminishing the number of wars, ecclesiastical influence has actually and very seriously increased it.

The animal world being altogether external to the scheme of redemption, was regarded as beyond the range of duty, and the belief that we have any kind of obligation to its members has never been inculcated - has never, I believe, been even admitted - by Catholic theologians.

Terror is everywhere the beginning of religion.
