Most of the pioneers of science and rational thinking were religious. One can believe in one thing based on logic and evidence and still have beliefs that aren't as well grounded. Newton was a genius and paved the way for so many things, yet dabbled in the mystics and alchemy. Doesn't downplay his science work.
Yep, for most of history what we'd call "science-ing" was done by people called natural philosophers, people who blended early scientific thought with questions of theology (ex. "How can I understand what God built outside our planet?")
Bruno was tried for heresy by the Roman Inquisition on charges of denial of several core Catholic doctrines, including eternal damnation, the Trinity, the divinity of Christ, the virginity of Mary, and transubstantiation. Bruno's pantheism was not taken lightly by the church,[2] nor was his teaching of metempsychosis regarding the reincarnation of the soul. The Inquisition found him guilty, and he was burned alive at the stake in Rome's Campo de' Fiori in 1600.
The Catholic priest Georges Lemaitre, who died in 1966, discovered the Big Bang.
In Steven Hawkings' book A Brief History of Time, Hawking described meeting with the Pope and the Pope told him how the Big Bang theory was great but don't go searching for the cause of the Big Bang.
I think that perfectly illustrates the difference between scientists who are religious and the Church itself.
I think the whole Galileo Galilei affair demonstrates the attitude of the Church before and after the fact. Didn't the RCC finally forgive him (irrespective of admitting he was correct) in the 1990s?
Georges Henri Joseph Édouard Lemaître a Belgain Catholic priest and cosmologist who hypothesized the primeval atom beginning of the universe, now the Big Bang Theory
Pope Pius XI was so impressed and glad to have a scientific theory that informed a beginning of the universe (where God could be inserted) that he gave Lemaître a promotion... right out of the astronomical department.
Lemaître, who was a much better scientist and mathematician than he was a bureaucrat petitioned his way back into astrophysics, not amused by how God works in mysterious ways, sometimes.
I mean, this is Catholic, a specific branch of Christianity. Fundamentalists like Jack Chick think that Catholicism is devil-worship, but I'm sure these people would be like, "yeah, he's a weirdo, but I wanna laugh at atheists, not actual crackpots!"
