The danger of refusing to reflect upon the psychological dynamics of faith and belief is that what we feel to be self evidently true, for psychological reasons, might be, upon inspection, highly questionable, intellectually or morally. Too often, as we all know, the 'feeling of rightness' trumps sober reflection and moral discernment. Further, we are often unwilling to listen to others until we are, to some degree, psychologically open to persuasion. The Parable of the Sower comes to mind.
In short, the Lord's Supper was the realization of new social and political arrangements, the embodiment of the social leveling seen in Jesus' ministry, most profoundly in his acts of table fellowship. Importantly, as we have seen, these new social arrangements could only be achieved if the emotions of social stratification were confronted, eliminated, or reinterpreted. In his body metaphor, Paul dramatically reframes these heretical emotions, the emotions of contempt, disgust, honor, and social presentability. Rather, than signaling exclusion and division - the natural expulsive impulse inherent in these emotions - Paul suggests that these emotions should signal just the opposite in the Kingdom of God: honor, care, and embrace.
