Origen

“ Now we make these remarks, not to disparage Plato (for the great world of men has found even him useful) , but to point out the aim of those who said: “And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power, that our faith should not stand in the wisdom of men, but in the power of God.” [4] For the word of God declares that the preaching (although in itself true and most worthy of belief) is not sufficient to reach the human heart, unless a certain power be imparted to the speaker from God, and a grace appear upon his words ”

“ If, then, it should be granted with respect to certain points, that the same doctrines are found among the Greeks as in our own Scriptures, yet they do not possess the same power of attracting and disposing the souls of men to follow them. ”

“ And therefore the disciples of Jesus, men ignorant so far as regards Grecian philosophy, yet traversed many countries of the world, impressing, agreeably to the desire of the Logos, each one of their hearers according to his deserts, so that they received a moral amelioration in proportion to the inclination of their will to accept of that which is good. ”
