“…all men, due to the sin within them, always and in all relationships seek to ‘suppress’ [the] knowledge of God (Rom. 1:18). The natural man is such a one as constantly throws water on a fire he cannot quench” (Christian Apologetics, Cornelius Van Til, p. 118).
“[Reformed theology] holds that man’s mind is derivative. As such it is naturally in contact with God’s revelation. It is surrounded by nothing but revelation. It is itself inherently revelational. It cannot naturally be conscious of itself without being conscious of its creatureliness. For man, self-consciousness presupposes God-consciousness. Calvin speaks of this as man’s inescapable sense of deity” (Christian Apologetics, Cornelius Van Til, p. 115).
“…men are sinners. They have ‘an axe to grind.’ They want to suppress the truth in unrighteousness. They will employ their reason for that purpose” (Christian Apologetics, Cornelius Van Til, p. 107).
“When man became a sinner, he made himself instead of God the ultimate or final reference point. And it is precisely this presupposition, as it controls without exception all forms of non-Christian philosophy, that must be brought into question… The sinner has cemented coloured glasses to his eyes, which he cannot remove” (Christian Apologetics, Cornelius Van Til, p. 98).
“On account of the fact of sin man is blind with respect to the truth wherever the truth appears. And truth is one. Man cannot truly know himself unless he truly knows God. Not recognizing the fact of the fall, the philosophers, says Calvin, throw everything into confusion” (Christian Apologetics, Cornelius Van Til, p. 92).
“The differences between Protestantism and Romanism are not adequately indicated if we say that Luther restored to the church the true doctrines of the Bible, of justification by faith, and of the priesthood of all believers. The difference is rather that Protestantism is more consistently and Rome is less consistently Christian at every point of doctrine. It could not well be otherwise. Having inconsistency at one point of doctrine is bound to result in inconsistency at all points of doctrine” (Christian Apologetics, Cornelius Van Til, p. 89-90).
“The conception of man as entertained by modern thought in general cannot be assumed to be the same as that set forth in Scripture. It is therefore imperative that the Christian apologist be alert to the fact that the average person to who he must present the Christian religion for acceptance is a quite different sort of being than he himself thinks he is (Christian Apologetics, Cornelius Van Til, p. 85).”
On the sufficiency or finality of Scripture: “When the sun of grace has arisen on the horizon of the sinner, the ‘light of nature’ shines only by reflected light… The light of Scripture is that superior light which lightens every other light. It is also the final light (Christian Apologetics, Cornelius Van Til, p. 65).”
“When men dream dreams of a paradise regained by means of common grace, they only manifest the ‘strong delusion’ that falls as punishment of God upon those who abuse his natural revelation (Christian Apologetics, Cornelius Van Til, p. 71).”
“Scripture became necessary because of the covenant disobedience of Adam in paradise (Christian Apologetics, Cornelius Van Til, p. 69).”
