Does "these enterprises" refer to " religious beliefs"?

Or refer to " rites, rituals, prayers, social institutions, holidays, etc."?

Context:

Clearly, religion cannot be reduced to a mere concatenation of religious beliefs. Every religion consists of rites, rituals, prayers, social institutions, holidays, etc., and these serve a wide variety of purposes, conscious and otherwise. However, religious belief - that is, the acceptance of secific historical and metaphysical propositions as being true!ais generally what rnders these enterprises relevant, or even comprehensible. I share with anthropologist Rodney Stark the view that belief precedes ritual and that a
practice like prayer is usually thought to be a genuine act of communication with a God (or gods). Religious adherents generally believe that they possess knowledge of sacred truths, and every faith provides a framework for interpreting experience so as to lend further credence to its doctrine.
