When Jesus instituted the Lord's supper, He said: "This is My body which is given for you; do this in remembrance of me." From a logical standpoint, it would seem that His direction was given for either those present (which means the practice would have died off after the apostles died) or for all those for whom His body was given, which would be all believers. Certainly Acts and the corrections Paul sends to the churches shows the practice continued into the early church, and indeed, into the next 2000 years. (If I'm all off where the Greek is concerned, please let me know.) BTW, I'm a lady and I have no problem examining what we do as a church and why we do it -- and being able to give a reasonable answer to those who might ask.
