Is it possible to consider that the 30-year war was purely religious in nature?

At the very beginning of its origin, this war was a religious conflict, but soon it turned into a global political confrontation, where the interests of large European states were the main ones: England, Germany, Sweden, France, etc. Naturally, why, after the end of the war, states such as France and Sweden acquired new territorial possessions, which in fact had nothing to do with religion.
