Most scientific and technical innovations prior to the Scientific Revolution were achieved by societies organized by religious traditions. Ancient Christian scholars pioneered individual elements of the scientific method. Historically, Christianity has been and still is a patron of sciences. It has been prolific in the foundation of schools, universities and hospitals, and many Christian clergy have been active in the sciences and have made significant contributions to the development of science.
Historians of science such as Pierre Duhem credit medieval Catholic mathematicians and philosophers such as John Buridan, Nicole Oresme and Roger Bacon as the founders of modern science. Duhem concluded that "the mechanics and physics of which modern times are justifiably proud to proceed, by an uninterrupted series of scarcely perceptible improvements, from doctrines professed in the heart of the medieval schools". Many of the most distinguished classical scholars in the Byzantine Empire held high office in the Eastern Orthodox Church. Protestantism has had an important influence on science, according to the Merton Thesis, there was a positive correlation between the rise of English Puritanism and German Pietism on the one hand, and early experimental science on the other.
