Why was the relationship between Church

and science traditionally a difficult one?

Answer: Historians of science and of religion, philosophers, theologians, scientists, and others from various geographical regions and cultures have addressed numerous aspects of the relationship between religion and science. Critical questions in this debate include whether religion and science compatible, whether religious beliefs can be conducive to science (or necessarily inhibit it), and what is the nature of religious beliefs.

Explanation:

Because they are not a part of nature, supernatural entities cannot be investigated by science. In this sense, science and religion are separate and address aspects of human understanding in different ways. Attempts to put science and religion against each other create controversy where none needs to exist.
