As an explanation of the Form and Content of our beautiful and beloved Catholicism; the Holy Spirit gives us the hour glass as a working model. What does this mean?
Consider the hour glass, unmistakable in its form, design and purpose. It’s immediately recognizable; in its symmetry, its functionality and in its simplicity, no other structure is like it, no other structure can take its place. It is the Form. It is the way that it is, because it is the only way it can be. This is the Church.
The sand; each grain is exquisitely unique. Distinctively faceted, a shade apart from the rest, fashioned by God and honed by nature. This is the Content. Bathed in paradox, because the only element each grain truly shares is that each is different. Yet taken in their entirety, each is uniform, locked in perfect harmony with the rest. This is the Body.
We realize the Form can not be changed, rearranged or altered in any way. And nothing can be added or taken away from the content. Not even the most beautiful diamond among the sand, for nothing else belongs there. There can be no substitutes; there are no equivalents, for only a genuine and measured amount will work.
Simply put, the “Hour Glass” provides the best example of the Church. Without the Form the Content fulfills no purpose. Without the Content the Form has no function.
