I hope this is it. The Eucharist is opposite of how you describe it and has been the focus of Christian worship since the beginning. If you read the very earliest fathers you will see it there.
To me, as a sacrament, it would be like calling baptism or marriage 'filthy'. I'm not doubting your statement, but I can't see this conclusion from one who truly receives the sacrament.
Have done that many times in the past with no good result..
Have never seen it work to benefit here(FR either)..
