All history shows that, in exact proportion as nations advance in civilisation, the accounts of miracles taking place among them become rarer and rarer, until at last they entirely cease.

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

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.

[Middleton] contended that the religious leaders of the fourth century had admitted, eulogised, and habitually acted upon principles that were diametrically opposed, not simply to the aspirations of a transcendent sanctity, but to the dictates of the most common honesty.
