"Some people think that all the equipment you need to discuss religion is a mouth"

This quote by Herman Wouk suggests that some people believe that the only tool needed to go over religious beliefs is the capability to speak. This implies that the capability to communicate is the most important factor in talking about faith. It suggests that the ability to express one's thoughts and feelings is more crucial than any other tool or resource. This could be analyzed as a call to concentrate on the power of discussion and conversation when talking about religious beliefs, rather than counting on external resources. It might also be seen as a suggestion that the ability to interact is an effective tool in itself, and that it needs to be used to its fullest capacity when talking about religion. Eventually, this quote encourages us to utilize our words to talk about religious beliefs, rather than depending on external resources.
