There are some South Africans who have participated with pain up to this point in the service, and who now feel constrained not to take part in the Lord's supper, which is the essence of Christian fellowship (Mt 5.23-24). The reasons for this refusal are threefold.

In our country, by custom and by church decision which are defended theologically, black people are not permitted to partake of the Lord's supper in the NGK and the NHK.
The theological heresy which undergirds apartheid racism finds its origin in separate communion. Our refusal to participate is a choice for righteousness and a refusal to reinforce the Christian roots of our oppression.
These churches, which are members of WARC, have consistently refused to have genuine reconciliation with us black Christians, through a confrontation with the evil of apartheid and by participating in the search for justice and peace and true humanity. To share communion with those who represent this disobedience to the gospel would mean eating and drinking judgement upon ourselves. "For if he does not recognise the meaning of the Lord's body when he eats the bread and drinks from the cup, he brings judgement upon himself as he eats and drinks." (1 Cor 11.29).
Our refusal to participate anticipates the day of our freedom when we shall all - black and white - drink from one cup and eat from one loaf.
