An engineer I met in Japan once talked with me about how he had come to trust in Jesus Christ. He shared that when he came to the church he was moved by how welcoming everyone was. He was welcomed to attend. He was welcomed to share meals together with them. He was welcomed to help out in various ways. And he was welcomed into people’s lives. He felt so welcomed, that after a little while, he said he could have gotten the impression that he was one of them. But every month when the church celebrated the Lord’s Supper, explanation was given that it was just for believers – it was the only time when he was ‘not welcome’ to participate. You would think it might have turned him off. In fact, it had the opposite effect. As he attended church each week, he felt himself growing nearer and nearer to Jesus and the teachings of the Bible, but at Communion he was reminded that there was a line he hadn’t yet crossed. He realized each time that he hadn’t yet opened the door of his life to faith in Jesus. And having yet refused to welcome Jesus’ work in his life by faith, he was not welcome to participate in the celebration of the work that the Lord’s Supper symbolizes. His story makes me wonder how many people have thought through who should participate in Communion and why. And why the Bible warns that participating in the Lord’s Supper “in an unworthy manner” leads to guilt and even judgment from God.
