Perhaps you missed the part when he said:
DO THIS IN REMEMBRANCE OF ME.
No, I caught that part. Are you doing it in "remembrance" or does your organization teach that it is more than that?
That right there is a key phrase. What did Jesus do? He took the common symbols of life giving sustenance, gave thanks for them, blessed them, and then gave them away. We can and should all do this. When we share our table and the gifts we receive, giving thanks and blessing them to good purpose - this is the true Eucharist. Anyone can make it. The Eucharist we receive at the hands of another has less value to us than it does to the person who makes it and gives it away. The value is in giving thanks and giving it freely. Kind of puts a different spin on "My flesh is true food", doesn't it? True food is my flesh, if you acknowledge where it comes from and aren't selfish with it.
For myself, I believe it is better to try to live and do as Jesus did - clothe the poor, feed the hungry, comfort the sick, share the gifts. Repeating magic words, praying to idols, and bowing down to a class of men who hold that they have unequaled access to the Holy Spirit - not so much.
Glad they don't burn heretics anymore.
