I once heard a story about a startling exhibit in Del Mar, California. A man took a glass beaker which had a small neck, but was enlarged to about seven inches in diameter below the neck. The beaker would hold about a quart. The demonstrator used the glass beaker as a hammer to drive a spike into a wooden plank. The glass was so well tempered that the beaker did not break. The man then took a small steel marble or bearing the size of a pea, and holding it at the neck of the beaker, dropped it inside. When it struck the bottom the glass was shattered and the beaker was broken from within.
The Church of our Lord, when perfectly united and tempered together with love, can resist the heaviest of blows from the outside. But just a small force on the inside can destroy this unity and harmony.
