Surely everyone will agree that it would have been a sin for Noah to have built the ark out of cedar wood. Everyone will likewise agree that it would have been wrong for the Jews to have offered a cow as a passover sacrifice. By the same line of reasoning, and just as clearly to be seen, it would be wrong today for people to substitute some other kind of music for the kind that God has specified. 2. The commandment to eat the Lord’s supper in memory of Jesus Christ is generic in some respects and specific in others. The Bible specifies the day of the week upon which this institution shall be observed. This lesson is taught by means of divinely approved example as recorded in Acts, chapter 20 and verse 7: “Upon the first day of the week when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight.” The Bible therefore specifies that the Lord’s supper shall be observed upon the first day of the week, but this teaching is generic as far as the hour of the day is concerned. There have been people who argued that it would be a sin to eat the Lord’s supper at 7:30 P.M. There are others who believe it is wrong to eat it at 11:00 A.M., just because the Bible does not specify that hour. But the same objection could be raised to any other hour mentioned, and thereby eliminate the possibility of eating it at all. The commandment to eat the Lord’s supper upon the first day of the week, necessarily implies that it should be eaten at _some_ hour, and God has seen fit to leave man free to use his own judgment in selecting the hour of the day. The Bible specifies that the fruit of the vine shall be used, but it does not say whether that fruit shall be fermented or unfermented. The failure to recognize this fact has led some to contend that it’s a sin to use grape juice. The very same type of error has caused others to contend that it would be wrong to use wine. We must recognize the fact that God has left this commandment generic as to whether the fruit of the vine shall be fermented or unfermented. Likewise the Bible does not designate the number of cups that shall be used, leaving us free to use our own judgment upon that point as well. It is true that the Bible refers to “the cup,” but every careful student knows that that refers to the contents and not to the vessel. As a matter of fact, there must be some distribution made between the original container and the lips of those who partake. The Bible does not specify at what stage this distribution shall be made. God has endowed us with intelligence, and expects us to use it in applying these commandments which are left in generic form.
