No, Darwin was not a devoted Christian. He was actually an agnostic or atheist. There has NEVER BEEN ANY DEVOTED CHRISTIAN SCIENTIST because Christianity, like the other religions, tends to prevent its followers from exploring the world.
Interesting point of view, giving the following:
Charles Robert Darwin was born at Shrewsbury. His father was a doctor and his mother was the daughter of Josiah Wedgwood. Darwin first studied medicine at Edinburgh. Will as they might, it soon became clear to the family, and particularly to young Charles, that he was not cut out for a medical career; he was transferred to Cambridge (Christ's Church, 1828), there to train for the ministry. Darwin actually imported and paid to have distributed in England Asa Gray's pamplet,
Natural Selection is not inconsistent with Natural Theology. Darwin discounted the reliability of the Old Testament, certainly Genesis, but he still held to beliefs that God was the ultimate lawgiver in the universe. Nothing in his studies caused him to conclude otherwise. What did effect Darwin strongly with regard to his religious beliefs was the death of his daughter. Following that, Darwin became more and more agnostic as he could not understand God taking his child from him. Thus is was not science but human emotions that produced the views you cite him as holding.
Though he was not a Christian, I find it interesting that Albert Einstein would take exception to your more general views: Here is what he said in answer to a letter from a child in a New York City Sunday School class, dated 24 January 1936:
Every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe — spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble. In this way the pursuit of science leads to a religious feeling of a special sort.
As for your statement "There has NEVER BEEN ANY DEVOTED CHRISTIAN SCIENTIST because Christianity, like the other religions, tends to prevent its followers from exploring the world." It really is two seperate statements:
1) There NEVER has been ANY devoted Christian scientist.
and
2) Christianity tends to prevent its followers from exploring the world.
Rather strong and universal statements. Both are categorically false.
Max Planck, a physicist and founder of quantum theory, was a devouted Christian. William Thomson Kelvin, George Gabriel Stokes, and James Clerk Maxell were all famous 19th century physists who did the truly exploratory research into the world of atomic theory and were also commited Christians.
Some other devout Christians who, no doubt by your standard, were scientific lightweights include:
Nicholas Copernicus (1473-1543)
Copernicus was the Polish astronomer who put forward the first mathematically based system of planets going around the sun. He attended various European universities, and became a Canon in the Catholic church in 1497. His new system was actually first presented in the Vatican gardens in 1533 before Pope Clement VII who approved, and urged Copernicus to publish it around this time. Copernicus was never under any threat of religious persecution - and was urged to publish both by Catholic Bishop Guise, Cardinal Schonberg, and the Protestant Professor George Rheticus. Copernicus referred sometimes to God in his works, and did not see his system as in conflict with the Bible.
Sir Francis Bacon (1561-1627)
Bacon was a philosopher who is known for establishing the scientific method of inquiry based on experimentation and inductive reasoning. In De Interpretatione Naturae Prooemium, Bacon established his goals as being the discovery of truth, service to his country, and service to the church. Although his work was based upon experimentation and reasoning, he rejected atheism as being the result of insufficient depth of philosophy, stating, "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."
Johannes Kepler (1571-1630)
Kepler was a brilliant mathematician and astronomer. He did early work on light, and established the laws of planetary motion about the sun. He also came close to reaching the Newtonian concept of universal gravity - well before Newton was born! His introduction of the idea of force in astronomy changed it radically in a modern direction. Kepler was an extremely sincere and pious Lutheran, whose works on astronomy contain writings about how space and the heavenly bodies represent the Trinity. Kepler suffered no persecution for his open avowal of the sun-centered system, and, indeed, was allowed as a Protestant to stay in Catholic Graz as a Professor (1595-1600) when other Protestants had been expelled!
Galileo Galilei (1564-1642)
Galileo is often remembered for his conflict with the Roman Catholic Church. His controversial work on the solar system was published in 1633. It had no proofs of a sun-centered system (Galileo's telescope discoveries did not indicate a moving earth) and his one "proof" based upon the tides was invalid. It ignored the correct elliptical orbits of planets published twenty five years earlier by Kepler. Since his work finished by putting the Pope's favorite argument in the mouth of the simpleton in the dialogue, the Pope (an old friend of Galileo's) was very offended. After the "trial" and being forbidden to teach the sun-centered system, Galileo did his most useful theoretical work, which was on dynamics. Galileo expressly said that the Bible cannot err, and saw his system as an alternate interpretation of the biblical texts.
Rene Descartes (1596-1650)
Descartes was a French mathematician, scientist and philosopher who has been called the father of modern philosophy. His school studies made him dissatisfied with previous philosophy: He had a deep religious faith as a Roman Catholic, which he retained to his dying day, along with a resolute, passionate desire to discover the truth. At the age of 24 he had a dream, and felt the vocational call to seek to bring knowledge together in one system of thought. His system began by asking what could be known if all else were doubted - suggesting the famous "I think therefore I am". Actually, it is often forgotten that the next step for Descartes was to establish the near certainty of the existence of God - for only if God both exists and would not want us to be deceived by our experiences - can we trust our senses and logical thought processes. God is, therefore, central to his whole philosophy. What he really wanted to see was that his philosophy be adopted as standard Roman Catholic teaching. Rene Descartes and Francis Bacon (1561-1626) are generally regarded as the key figures in the development of scientific methodology. Both had systems in which God was important, and both seem more devout than the average for their era.
Isaac Newton (1642-1727)
In optics, mechanics, and mathematics, Newton was a figure of undisputed genius and innovation. In all his science (including chemistry) he saw mathematics and numbers as central. What is less well known is that he was devoutly religious and saw numbers as involved in understanding God's plan for history from the Bible. He did a considerable work on biblical numerology, and, though aspects of his beliefs were not orthodox, he thought theology was very important. In his system of physics, God is essential to the nature and absoluteness of space. In Principia he stated, "The most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion on an intelligent and powerful Being."
Robert Boyle (1791-1867)
One of the founders and key early members of the Royal Society, Boyle gave his name to "Boyle's Law" for gases, and also wrote an important work on chemistry. Encyclopedia Britannica says of him: "By his will he endowed a series of Boyle lectures, or sermons, which still continue, 'for proving the Christian religion against notorious infidels...' As a devout Protestant, Boyle took a special interest in promoting the Christian religion abroad, giving money to translate and publish the New Testament into Irish and Turkish. In 1690 he developed his theological views in The Christian Virtuoso, which he wrote to show that the study of nature was a central religious duty." Boyle wrote against atheists in his day (the notion that atheism is a modern invention is a myth), and was clearly much more devoutly Christian than the average in his era.
Michael Faraday (1791-1867)
Michael Faraday was the son of a blacksmith who became one of the greatest scientists of the 19th century. His work on electricity and magnetism not only revolutionized physics, but led to much of our lifestyles today, which depends on them (including computers and telephone lines and, so, web sites). Faraday was a devoutly Christian member of the Sandemanians, which significantly influenced him and strongly affected the way in which he approached and interpreted nature. Originating from Presbyterians, the Sandemanians rejected the idea of state churches, and tried to go back to a New Testament type of Christianity.
Gregor Mendel (1822-1884)
Mendel was the first to lay the mathematical foundations of genetics, in what came to be called "Mendelianism". He began his research in 1856 (three years before Darwin published his Origin of Species) in the garden of the Monastery in which he was a monk. Mendel was elected Abbot of his Monastery in 1868. His work remained comparatively unknown until the turn of the century, when a new generation of botanists began finding similar results and "rediscovered" him (though their ideas were not identical to his). An interesting point is that the 1860's was notable for formation of the X-Club, which was dedicated to lessening religious influences and propagating an image of "conflict" between science and religion. One sympathizer was Darwin's cousin Francis Galton, whose scientific interest was in genetics (a proponent of eugenics - selective breeding among humans to "improve" the stock). He was writing how the "priestly mind" was not conducive to science while, at around the same time, an Austrian monk was making the breakthrough in genetics. The rediscovery of the work of Mendel came too late to affect Galton's contribution.
