What, have we all forgotten Copernicus and Galileo, to say nothing of Darwin? Galileo, if you will recall, was harshly punished for his assertion that the earth moved around the sun. Of course, the Church did admit to its mistake. When did they do this? 1992, when a commission appointed by Pope John Paul II determined that the previous stance was based on an excessively narrow interpretation of the Bible. That means that heliocentrism has been a part of official Church doctrine for only seven years. So, yes, the Catholic Church has cleaned up its act in recent years, but… 1992? Come on…
The Catholic Church invented science? As I recall, the scientific method as we know it was the brainchild of a monk named Roger Bacon, who insisted that one’s perceptions of the natural world should be influenced by observation, and thus contradicted the writings of St. Thomas Aquinas and the rest of the Catholic mainstream who believed that faith, and faith alone was the key. This (the former) was not a viewpoint that was popular at the time, and very little in the way of real science was done in Europe during the time that the Church held sway, what little there was being more along the lines of innovation in agricultural techniques. Charlemagne may have encouraged literacy among his subjects, but such things were the exception, not the rule.
And as for the Muslims, pagans, and men of science, yes, there have been abuses. Such abuses usually occur when someone decides that their worldview is the only correct one, as the Church has for centuries. During the Dark Ages of Europe, many advances in the fields of medicine, astronomy, optics, and mathematics were being made in the Islamic world. It wasn’t until some overzealous clerics started seeing a threat to their faith in scientific inquiry, that science became a naughty word. Abuses by “men of science” are usually by men so caught up in their science that it becomes a religion to them, and other things, like ethics and the sanctity of human life, fall by the wayside. Zealotry in any form is a terrible thing, and should be avoided. Myopic? It doesn’t get much more myopic than that.
In short, perhaps I should not be picking on the Catholic Church alone (which may or may not have been the point of the OP). And, as I admitted earlier, the Church is at least making an attempt to rehabilitate itself. The fact remains, that the Church has done much to cause human suffering in the past centuries. My original post still stands.
