Is it possible that a single letter can change an entire teaching relative to something like the mark of the beast? What might the mark be if it is "on" the hand or forehead? What might the mark be if it is "in" the hand or forehead? Is one's view of the mark, described in Revelation 13:16, determined according to whether or not one believes the mark is something that goes in the hand/forehead or on the hand/forehead? Or are these differences irrelevant? What is the reason or reasons why the traditional Bibles have "in" and the modern versions have "on"? Are the traditional Bibles correct are the modern versions correct or are they both correct or both wrong? Please keep comments focused on one or more of the above listed questions and let's play nice.
