ANSWER: The day before he died he said (John 16:12), "I have yet many things to say unto you, but ye cannot bear them now. When the spirit of truth is come, he shall guide you into all the truth." Everybody will admit that the treatment of the Sabbath was the most ticklish subject Christ had to deal with in all his intercourse with the Jews. Again and again did he rebuke their impracticable misconceptions, making it the most dreaded, distressing and awful day of the seven. If he had desired to divest it of the severities with which it was loaded down, he could not have done it without changing the day; and he could not change the day without breaking down the confidence of everyone of his apostles and disciples. Hence he left it for the Holy Spirit to teach, who did thus teach so that they immediately began to keep the first day. (John 20:19, 26; Acts 20:7; I Cor. 16:2; John 1:10, on the Dominical Day, i. e., Sunday). As the result the whole Christian world, except a little handful, keeps the first day. To cure this handful get them to go eastward round the world, and when they get home they will all be keeping the first day, having gained a day. Perhaps Carnegie or Rockefeller can be persuaded to pay the bills in order to rid the Christian world of this senseless clamor against it of a few discordant voices.
