ANSWER: Indirectly by Christ on the day before his crucifixion, when he relegated to the Holy Spirit the many things the disciples could not then bear (John 16:12, 13), and directly by the church filled with the Spirit on the day of Pentecost (Acts 20:7; I Cor. 16:2; Rev. 1:10). "I was in the Spirit on the Dominican Day;" the adjective Dominican described the Lord's Supper (I Cor. 11:20). This shows that the Lord's Day kept by John is not Jehovah's day; but the first day. Christ had much trouble with the Jews about the Sabbath. If He had made the change, His disciples were so weak as not to be able to bear it; some Christians even are so infantile that they cannot bear it now. Let them go eastward around the world, keeping every seventh day, and when they get back, having gained a day, they will be keeping the first.
