Página 224 - Christ not risen; and if Christ be not risen, then is our preaching vain, and your faith is also vain. Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ; whom he raised not up, if so be that the dead rise not. For if the dead rise not, then is not Christ raised; and it" Christ be not raised, your faith is vain; ye are yet in your sins.
Página 224 - Now, if Christ be preached that he rose from the dead, how say some among you that there is no resurrection of the dead ? But if there be no resurrection of the dead...
Página 191 - It appeareth in nothing more, that atheism is rather in the lip than in the heart of man, than by this; that atheists will ever be talking of that their opinion, as if they fainted in it within themselves, and would be glad to be strengthened by the consent of others. Nay more, you shall have atheists strive to get disciples, as it fareth with other sects. And...

Página 191 - It is true that a little philosophy inclineth man's mind to atheism, but depth in philosophy bringeth men's minds about to religion. For, while the mind of man looketh upon second causes scattered, it may sometimes rest in them and go no further, but, when it beholdeth the chain of them confederate and linked together, it must needs fly to Providence and Deity.
Página 192 - It destroys likewise magnanimity, and the raising of human nature ; for take an example of a dog, and mark what a generosity and courage he will put on when he finds himself maintained by a man ; who to him is instead of a God, or melior natura ; which courage is manifestly such as that creature, without that confidence of a better nature than his own, could never attain.

Página 192 - God, or melior natura; which courage is manifestly such as that creature, without that confidence of a better nature than his own, could never attain. So man, when he resteth and assureth himself upon divine protection and favour, gathereth a force and faith which human nature in itself could not obtain. Therefore, as atheism is in all respects hateful, so in this, that it depriveth human nature of the means to exalt itself above human frailty.
