A couple years ago I had a revelation about communion and the reason behind it. You can read that here. I went back and read it. I still think this is the most important part of communion is the memory that it inspires. In that other post, I wrote:
I never really understood the reason for Communion. I mean, I understood it intellectually; I knew we did it because we were told to do so. I didn't understand why it mattered though. I never knew the emotional value of this simple meal. Now I understand, even as trivial as this analogy may seem, it really has opened my eyes to the beauty of this act of worship. People come together over food. Jesus understood that and used it to our benefit. We remember who we belong too and who's family we are in. It's almost as if He was implementing a family dinner where we share more than food with one another. We share life and we celebrate life together with this simple act of taking Communion. This fact is truly beautiful to me and I am so grateful to understand it on a new level. I hope someday you also can understand this as I do today.
Honestly, I think that is all I can say on the subject.
