Mark 14:23
The cup was shared. We cannot really get around that. It seems quite obvious from the wording here. However, so was the bread. Just as the bread was divided in order to be shared, the cup likely was as well. As long as we understand the symbolism, that we are all drinking from the same source, that is the main thing. It is not absolutely necessary to all drink from the same physical cup.
Heavenly Father, thank you for the precious blood of Christ shed for us. We can never praise you enough for the forgiveness we may have in Him. You are truly gracious, and your love is clear. In the name of the Lord Jesus Christ I pray and praise you, Amen.
