This is a Eucharist chant by Michael Herry fms. This chant says about all that needs to be said. If you go here and scroll to the bottom of the page you will find an MP3 and the sheet music. For some reason the version I have in in G, but the downloadable version from the Marists is in Ab.
Lord, we come to your table.
Lord, we hear your word.
Lord, you are our bread of life,
and we the Body of Christ.
