Is religion more cultural than spiritual?

The more I think and learn about religion in general, the more I wonder what holds it together and I come to the conclusion that “faithful” relate much more to the tribal, communal and ritual aspects of religions than its theological basis. 

The spiritual part is of course the weakest part of the religious edifice, as it is for the most part, totally irrational and impossible to prove. 

This is a place where members of religion don’t venture very far because nothing really makes sense to them, and if they dig deeper, risk negating what they know in terms of their factual and pragmatic experience of life. 

They tend to leave the theological part to the “experts”, in other words, their leaders who are free to tell them whatever they want.

So for me, religions are more the cultural expression of buildings, history, community activities and a rich ritual that glue the members together and keep a specific spiritual community going.

When put under the microscope, the real story behind religion doesn’t hold much credence and explain why members of religion don’t choose to venture there and stick quietly and obediently to the tangible, ritual portion of religion and the tribal support it represents for them...
