So why do you defend communion?

Recently on Facebook there was a picture of what is depicted as Messiah holding bread in one hand and a cup in the other. I was just a bit on the livid side, because the bread was a yeast bread and being sold as the "last supper." I spent 3 days with posts back and forth explaining and not wavering in my stand that the picture is incorrect from a scriptural standpoint and a man made tradition. When Messiah said to "do it in remembrance of Him." It was at the Passover Seder, not to institute a weekly or monthly tradition to serve bread or a communion wafer, that BTW tastes like rice paper not bread, grape juice or wine and do this on Sunday, the venerable day of the sun.
I went on and on combating all the so called accusations of what they kept trying to say that I was saying. They weren't even quoting me correctly. So I kept defending what Torah actually says, utilizing the fact that all the verses I was using is backed up by 2-3 others. So I let scripture interpret scripture. Not my words, but YHVH's. It was a great experience overall. It was sharpening me and letting me use the ability to recall YHVH's Words when I needed them the most. Let alone, I was reading His Word, recalling all His precious words and deeds. I was being used by YHVH to spread His light in this dark and dying world. I was so humbled by the experience as well. Because I felt that the ignorant words being thrown back at me could be me still stuck at that "stinkin' thinkin." I really felt what YHVH's mercy really is. He has been so gracious to me and my husband to have brought us out of "Babylon" that I am so grateful. It really is rightful that I am out there defending the faith.
