In a vineyard, a trellis is essential to lift the vine off the earth to maximize exposure to sunlight. There are thousands of different types of trellis. The trellis is a good analogy for the same need for order and structure in a local church. The vine branches represent the fluid organic life of relationships in Christ, the trellis the hard edge of inflexible order. The sap of the vine represents the agape flowing in the veins of the branches of the vine. And the grapes, the bounty from the trellis and vine working together.
