Religion
There is no scholarly consensus over what precisely constitutes a religion. It may be defined as a cultural system of designated behaviors and practices, world views, texts, sanctified places, prophesies, ethics, or organizations, that claims to relate humanity to supernatural, transcendental, or spiritual elements.
Theology
When all is said and done, science is about things and theology is about words. Things behave in the same way everywhere, but words do not. ... Theology works in one culture alone. If you have not grown up in Polkinghorne's culture, where words such as "incarnation" and "trinity" have a profound meaning, you cannot share his vision.
Freeman Dyson, The Scientist As Rebel (2006).
