The wonderful mystery of Many Yet One applies to all we do and believe as Saints. We are one body, not as a family or as a church location, but we are one body with all Saints throughout history with God the Son as the head of this body. As members of this one body, we do not have the privilege to read the Bible for ourselves and decide for ourselves what it means. Neither may we just listen to a pastor of a local church and submit to his teaching. We must not solely submit to a pastor, bishop, or Pope. We definitely are not to listen to a variety of pastors and read a variety of books and then pick and choose what we believe. As members of this One Body, our beliefs are not of ourselves. Our beliefs are part of a belief system developed by the community of Saints throughout history. Every spiritual idea, every spiritual thought, must be in subjection to this community of Saints.
Part of mankind’s depraved nature is that we are arrogant enough to believe that we can add to a historical debate. After 2000+ years of the Christian era, and many thousands of years of Saints before Christ, we are arrogant enough to think we can develop a new idea that no Saint has every conceived before.
For the entire Christian era, theologians have debated predestination and free will. Does God predestine our choices or do we have free-will to make our own choices? Saints throughout history have debated this question and have never come to a consensus. Isn’t it arrogant of us to believe that we can add to the debate after 2000 years? Instead, if we submit to the communion of Saints throughout history, we realize the exact answer to this question is a wonderful mystery that has no answer.
As we examine the theology of the communion of Saints, we see a simple, yet profound systematic theology. We see a wonderful, yet mysterious Trinity of God the Father, God the Son, and God the Spirit. We see a God of justice, yet a God of mercy. We see a story of creation, redemption, and resurrection. We see a hope of a future return of God the Son, and a regaining of community with the Trinity.
