You have heard of South Africa’s “apartheid” policy. Here is how it began: in churches. In 1828, a Malaysian slave brought her dark-skinned husband to church there. The official teaching of the Dutch Reformed Church was that no one should be discriminated against concerning communion. But some of the whites were offended that this man would be sharing the Lord’s Supper with them. The leaders of the church knew these whites were “weak” in knowledge, but quoted 1 Corinthians 8:13, and ordered the dark-skinned man to stay away.
The essential issue here was not discomfort during communion, but the exclusion of a person “for whom Christ died.” Paul would never agree with what they did.
