If religion is to create the conditions for a connection with the Deity that is “real,” religion must necessarily be conceptualized and implemented in particular cultural contexts where such a relationship may be experienced, not in a vacuum; otherwise, its claims would become obscure abstractions, a bunch of weird ideas floating up in the air or crazy aspirations no one would understand or relate to. Contextualization is the key. Thus, to be relevant, communicable, and understood, religious faith needs to be mediated.
It is obvious that for this contextualization to be viable, religious communities are required to heavily depend on what cultures can offer as “rough materials,” namely, as resources of meaningful interactions, otherwise how would religious ideas be conveyed and understood if this is not done on the basis of what people are familiar with? In this process whereby religion assimilates and reformulates the contributions of cultures to mediate the relationship with the Sacred, a concomitant tactic will be the use and appeal to all human senses (sight, touch, smell, hearing, and sight), at the service of a sixth and more important one; namely, the belief in a metaphysical realm and unknown, very powerful forces therein.
Defined this way, how does religion initiate and cultivate a relevant relationship with the Sacred that is contextually-grounded and relevant to the believers and potential converts?
To begin with, I believe that religion sacralizes social reality in light of what it assumes to be true about God. Colored by this assumption, certain people, ideas, values, objects, places, times, animals, and symbols are no longer ordinary or secular, but filled with ultimacy and, because of it, set apart or holy. More specifically, and through its many cultural manfestations, religion creates and resorts to the following general, tangible strategies to create and fortify a bond with the Deity:
1) A series of special rituals and symbols that serve as vehicles whereby to communicate particular ways of looking at the world and the people’s relationship with the Holy, primarily in the context of worship.
2) A body of formal, mandatory values and beliefs, usually crafted as creeds, resolutions, and doctrines, to meet the spiritual and intellectual life and death needs of the groups. These are not simple teachings.
3) Oral traditions and/or texts that serve as objective foundations of people’s beliefs, values, and expected behaviors, which serve as ideological foundation and equally give to its members a sense of belonging, identity, and purpose.
4) A moral system derived from their relationship with the Holy, which contains rules and regulations to help people distinguish between right and wrong in order to facilitate their interaction with others and develop their character.
5) Organized sects with varying degrees of popularity and following. Internally speaking, world religions are not uniform. What we find is different, and sometimes conflicting, understandings of what it means to be a faithful believer.
6) Proselytizing strategies whereby to recruit, keep, and increase the number of followers to give continuity to the faith community. The initiatives to meet these goals vara considerably.
7) And finally, particular worldviews that embody and justify what the religion is and does, which may be inferred from everything it stands for. These worldviews influence, legitimate, and strengthen the believers’ ideology, and their place and role in the world.
All the above visible moves are common ground; they define a large number of religions in the world and, therefore, constitute relative criteria we should use in our analysis to better understand them. But let us not forget that, because every religion is a social construct seeking to facilitate a faith-encounter with a Supreme Reality in context, they will all develop their own unique personality in their understandings the Holy and the applications of such understandings. This means that we can only understand world religions when we take into account the particular settings, circumstances, and histories where they all emerged from and live their faiths. For this very reason, religions must always be studied in terms of similarities and differences.
 For a more formal definition of religion, please see my post “What is Religion? Naming a Faith-Driven Experience,” http://blogs.reinhardt.edu/ich/2017/01/25/what-is-religion-naming-a-faith-driven-experience/
 One implication of this statement is that we cannot fully understand religion without understanding its culture and vice versa.
 This means that all religions may and should be studied focusing on these seven areas.
