I don't see it about being just loving other people, but also fidelity to a receive tradition (in this case, a tradition of God himself). You cannot change the eucharistic elements to be something other than what Christ himself said they were.
Yet as Jesus and his disciples were celebrating a Passover meal, they would have had unleavened bread; bread made without yeast, that would not have risen and been quite flat.
If you want to talk about changing things, any church that offers white/brown/wholemeal, risen bread at communion has already done that.
But what kind of bread you offer does not change the fact that Jesus is the bread of life, his body was broken for us and he died for us to reconcile us to God.
Jesus is the 2nd Moses who freed us from slavery to sin and death; he was the Passover Lamb who was killed for us, 1 Corinthians 5:7. He is the Bread of Life, John 6:35, and the True Vine. John 15:1. At communion/Eucharist we remember his death and all that he has done, and made possible, for us. That doesn't change - and I can't believe that God is going to be seriously offended if we use white/brown/wholemeal bread, gluten free bread or a cracker. My friend who is coeliac has been having rice crackers for years. He is a lovely, sincere Christian and a lay preacher; God doesn't seem to have struck him down yet.
Those who cannot receive communion are not excluded from participation altogether at many churches, they can come forward to the altar for a blessing.
But they are being denied communion; participation in the Lord's Supper. It would be like saying to them, "you messed up, got drunk and became addicted to alcohol. You cannot receive the blood of Christ - which by the way will cleanse you and make you whole - because we choose to use real wine."
(Whether anyone ever fell off the wagon through one sip of communion wine anyway, is debatable.)
I am surprised those who focus on baptism and the Lord's Supper being about a divine ordinance that requires obedience would have a problem understanding this.
I'm surprised to find a thread that seems to imply that unless you are using the exact same elements in communion that Jesus used at the Last Supper, you are somehow cheapening communion.
Like I said, they ate a Passover meal and Jesus would have taken unleavened bread. Is that what happens at your church; a full Passover meal with lamb, herbs and unleavened bread? No? Well maybe you aren't "following the Bible" either.
And do you really think that the Lord who knows and understands all our weaknesses would exclude certain people from his Eucharist - or that he would punish the churches who used non alcoholic wine, instead of fermented wine, to commemorate his shed blood?
