Because ?  Or... "just as" religion is the physical manifestation of social structure. 

'Because' talks about causality and it seems to me morality appears in groups before religion does.

 
Everything else you wrote makes sense to me.  Culture seems to me to mean a set of designs of behaviours and norms, to apply to some group.  National identity is that, too.  But none of them quite fit.

Morality feeds into religion. Religion is the physical representation of morality through rituals and artifacts. Morality is the external force of aggregate social action that influences individual agency.
