1) As far as "I know" church history, I was raised in
the Christian Churches, those which were like
Churches of Christ, but they were used to play with instruments before the ONE you attend changed men´s TRADITIONS.
2) What a person "feels" as a sin is not and could be not, a sin for another, so -senses or ideas- do not relate to sins, unless these break GOD´s will.
3) The OT is full of times when INSTRUMENTAL music was "played" at services... Just have a look on David´s dancing. He was a king dancing "before" God (and being seeing by men and their women. Did he sin? Perhaps and perhaps not. David´s wife criticized his SHOWY dancing BUT David knew his own reasons to dance (I like dancing) (It makes me express my joy and my freedom to move and enjoy the music I hear).
4) I would agree the some PLAYERS would like to be seen and admired. Those who SING or PLAY music think they are VERY important during church service (Is it true?) But, as I have seen in some churches, those players are hidden behing a shade or curtains (just to avoid being showy, to hinder some selfcenterness) so, id I had to play or sing in a church like that, I´ll be glad to hide my face and my vanity, just for the sake to move my brethens into another level of WORSHIPPING GOD.
5) Have you ever attended a concert? Those go have gone feel what they feel and, if we go to heaven, music and angelic voices would be raised so, will your destroy instruments? Will you kill the music that stirs people to seek GOD by attending such services? I do agree Christians Churches aren´t a social CLUB, not a theater and certainly not a rock concert, but I have like PETRA, I like TFK and a couple of Christian musician who play well, instead of listeneing to the EROTIC SALSA I absolutely hate and, if it be taken to church, I would burn my ears...
