I would love to keep my cell phone at home but you see, I need it for my hearing aids. They are located ON the cell phone. I need to turn them on - on the cell phone. I need to turn my t-coil on so the audio-loop system in the church is in sync with my hearing aids. This way I can hear what the preacher is saying in the microphone during the service. Otherwise....I am deaf/hard of hearing. Then I might as well stay home. LCMS does not address this issue. I am NOT totally DEAF - I do not use ASL - sign language. THEN, I would stay home for sure. Most of our congregation uses the LOOP system in our church so they can hear well. You all ought to encourage other churches to do the same.
