Question: What is the Biblical basis for offering or observing the Lord's Supper twice on Sunday? 1. Caller recognizes that Sunday is the scriptural day for observing the Lord's Supper (Acts 20:7). 2. The number of times of assembling is not specified. 3. It is a reality, that due to shift work, and other factors, that some may be unable to attend the first service. Dick Blackford tells of a couple he knows which has a son who is mentally afflicted. The lady attends the morning assembly and the father attends the evening assembly. If he were not allowed to partake of the Lord's Supper at the evening service, conceivably, he could go a whole lifetime without communing with the Lord. Thus he would be refused the opportunity to do what Jesus commanded. 4. The scriptural basis for such being permitted to partake the Lord's Supper is that a) It is the first day of the week, as set forth in Acts 20:7; b) The church has assembled together on the first day of the week; c) For the one partaking, it is not a second observance, it is the first observance for him. Consubstantiation 1. The doctrine that in the Lord's Supper, the bread remains bread, and the wine remains wine; but that with and by means of the consecrated elements the true natural body and blood of Christ are communicated to the recipients. It differs from Transubstantiation in that it does not imply a change in the substance of the elements (Mc.&Str.II.492).
