After our previous article on prayer, we have done some study on the traditions and customs that surround prayer. One of the topics that have come up in our discussions about prayer, is the use of tefillin or phylacteries. People wonder if the Jewish interpretation of Scripture is valid. Should we interpret the verses literally as they do? Should we also be using these black boxes when we pray? Or, did the church fathers get it right when they said this is not to be taken literally? We investigate what Scripture really says to see if we can come to a conclusion.
