Amen. Emphasis on "sharing." I like what James Jordan says about the communal aspects of the Lord's Supper, as opposed to an exercise of private devotion between an individual and God. ...
Worship is covenant renewal, and the communion meal is always the climax of God's renewing covenant with His community. This way of putting it takes the focus off of what is "extra" about communion, and puts the focus on God's renewing of the covenant in the whole service. It also takes the focus off of any notion of an individual's getting some kind of "fix" from communion, and puts the emphasis on the community."
Reading St. Paul I definitely get that communal sense, and joyfully so! The joy of Paul is just contagious!
