How does a menorah represent Christ and the Church?
Remember Jesus’ discourse in John 15 about “I AM the vine. You are the branches?” A menorah has six branches coming up from a central one. 6 is the number of man (That’s both guys and gals). Add one to make completion. That one is Christ. We aren’t complete without Him.
