Critique of Calvin's Institutes - Chapter 4

  "Hence, they do not conceive of him in the character in which he is manifested, but imagine him to be whatever their own rashness has devised. This abyss standing open, they cannot move one footstep without rushing headlong to destruction. With such an idea of God, nothing which they may attempt to offer in the way of worship or obedience can have any value in his sight, because it is not him they worship, but, instead of him, the dream and figment of their own heart. This corrupt procedure is admirably described by Paul, when he says, that “thinking to be wise, they became fools” (Rom. 1:22). He had previously said that “they became vain in their imaginations,” but lest any should suppose them blameless, he afterwards adds that they were deservedly blinded, because, not contented with sober inquiry, because, arrogating to themselves more than they have any title to 47do, they of their own accord court darkness, nay, bewitch themselves with perverse, empty show. Hence it is that their folly, the result not only of vain curiosity, but of licentious desire and overweening confidence in the pursuit of forbidden knowledge, cannot be excused." - John Calvin 

This argument is good for most parts but in the end , he expounds on Romans 1:22 and says that  "overweening confidence in the pursuit of forbidden knowledge, cannot be excused "
Scripture is so lucid . Romans 1
¹⁸ The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, ¹⁹ since what may be known about God is plain to them, because God has made it plain to them. ²⁰ For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
²¹ For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. ²² Although they claimed to be wise, they became fools ²³ and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
²⁴ Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. ²⁵ They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
²⁶ Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. ²⁷ In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.
²⁸ Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. ²⁹ They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, ³⁰ slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; ³¹ they have no understanding, no fidelity, no love, no mercy. ³² Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.




2."Nay, we have still stronger evidence of the proposition for which I now contend—viz. that a sense of Deity is naturally engraven on the human heart, in the fact, that the very reprobate are forced to acknowledge it. When at their ease, they can jest about God, and talk pertly and loquaciously in disparagement of his power; but should despair, from any cause, overtake them, it will stimulate them to seek him, and dictate ejaculatory prayers, proving that they were not entirely ignorant of God, but had perversely suppressed feelings which ought to have been earlier manifested."  
                                                                                                      - John Calvin


Inspite of no biblical teachings , passages backing his position , Calvin feels that he has "still stronger evidence " from what the reprobate do.
His assumption about the reprobate that they ejaculate prayers in times of trouble is nothing more that what it is , assumption.
To say that assumption is still stronger evidence to prove his false premise that a sense of deity is naturally engraven on human heart is to prove stronger evidence that he is wrong and wanting in true evidence.

Inspite of it being a unbiblical argument , Calvin continues to claim that he has stronger evidence.

His attack on false religion and atheism is not bad. Here are some good points we can learn :
1.. It makes little difference, at least in this respect, whether you hold the existence of one God, or a plurality of gods, since, in both cases alike, by departing from the true God, you have nothing left but an execrable idol. It remains, therefore, to conclude with Lactantius (Instit. Div. lib 1:2, 6), “No religion is genuine that is not in accordance with truth.”
Good explanation which fits both Hinduism and Islam .

2.As a just punishment of the wicked, after they have closed their own eyes, God makes their hearts dull and heavy, and hence, seeing, they see not. David, indeed, is the best interpreter of his own meaning, when he says elsewhere, the wicked has “no fear of God before his eyes,” (Psalm 36:1); and, again, “He has said in his heart, God has forgotten; he hideth his face; he will never see it.” Thus although they are forced to acknowledge that there is some God, they, however, rob him of his glory by denying his power. For, as Paul declares, “If we believe not, he abideth faithful, he cannot deny himself,” (2 Tim. 2:13); so those who feign to themselves a dead and dumb idol, are truly said to deny God.
