The Lord's Table is a time of worship for believers. It is an ordinance instituted by our Lord on the night He was betrayed, as a memorial of His death. This ordinance is to be observed until He comes again.
The supper is a time of fellowship and communion with others of like faith wherein those who have trusted Christ gather as one to celebrate that which has made them one family born of one blood.
This feast is not a place of discipline where the church collectively forbids someone to partake. Since this is an ordinance of Christ, and therefore a command of our Lord, if the church were to forbid someone to partake of the elements, then the church would be forcing that person to disobey the command of our Lord.
Each believer is to examine himself on the basis of whether he discerns, (has a
vital understanding of, and a saving interest in) the body and blood of Christ,
represented in the elements of unleavened bread and wine. One is not to approach
the table examining himself on the basis of whether or not there is sin in his
life so that he can discern his worthiness or lack thereof to partake....that is
a foolish notion. Discerning the body and blood of Christ is, at its very heart,
a knowledge of personal unworthiness. Taking the Lord's Table is a confession
sin, not a confession of presumed righteousness.
