I would suggest the plurality of religions represent different human interpretive frameworks for understanding the Divine. Each interpretive framework represents a partial model, which is informed by time, place, culture, and history. All of the major world religions point in some way to the Divine; like the proverbial blind man and the elephant, each captures some element of a greater reality.
John Hick puts it this way in God Has Many Names:
We have a system for filtering out the infinite divine reality and reducing it to forms with which we can cope. This system is religion, which is our resistance (in a sense analogous to that used in electronics) to God. The function of the different religions is to enable us to be conscious of God, and yet only partially and selectively, in step with our own spiritual development, both communal and individually. (p. 112).The world religions often emphasize specific, sometimes complementary aspects of an all-encompassing and infinite Transcendent reality; some, for example, might focus on the personal aspects of the Divine, while others emphasize the nonpersonal. Hick suggests that
...we have to accept that the infinite divine reality is only knowable by man insofar as it impinges upon finite human consciousnesses, with their variously limited and conditioned capacities for awareness and response. But once we accept this, then the very plurality and variety of the human experiences of God provide a wider basis for theology than can the experience of any one religious tradition taken by itself. For whereas we can learn from one tradition that God is personal, as the noumenal ground of theistic experience, and from another tradition that God is the nonpersonal Void, as the noumenal ground of its form of mystical experience, we learn from the two together that God is the ground and source of both types of experience and is in that sense both personal and nonpersonal. (p. 110)In the proverb of the blind man and the elephant, one man senses the trunk, another the legs, another the tusk; all come up with some aspect of the Elephant-nature, and draw conclusions accordingly. But only by putting together all those parts of the elephant's body to you get a complete elephant, which, it turns out, is actually greater than the sum of all those individual parts.
