Someone posted a one-liner to Mastodon and I felt compelled to look it up.

«From all that I have attempted to say it should now be apparent that sincerity and conscientiousness in themselves are not enough. History has proven that these noble virtues may degenerate into tragic vices. Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity. Shakespeare wrote:

For sweetest things turn sourest by their deeds; 
Lilies that fester smell far worse than weeds. 

As the chief moral guardian of the community, the church must implore men to be good and well-intentioned and must extol the virtues of kindheartedness and conscientiousness. But somewhere along the way the church must remind men that, devoid of intelligence, goodness and conscientiousness will become brutal forces leading to shameful crucifixions. Never must the church tire of reminding men that they have a moral responsibility to be intelligent.

Must we not admit that the church has often overlooked this moral demand for enlightenment? At times it has talked as though ignorance were a virtue and intelligence a crime. Through its obscurantism, closedmindedness, and obstinacy to new truth, the church has often unconsciously encouraged its worshipers to look askance upon intelligence.

But if we are to call ourselves Christians, we had better avoid intellectual and moral blindness. Throughout the New Testament we are reminded of the need for enlightenment. We are commanded to love God, not only with our hearts and souls, but also with our minds. When the Apostle Paul noticed the blindness of many of his opponents, he said, “I bear them record that they have a zeal for God, but not according to knowledge.” Over and again the Bible reminds us of the danger of zeal without knowledge and sincerity without intelligence.»
