As I do the math, there are five great mysteries in theology:
1. Creation out of nothing (ex nihilo): How did God create being out of non-being? Being transcendent in relation to the universe (above all time, space, and matter), the reason for God’s being is necessary (hence why we often call him the “necessary being”), so his existence does not require a cause-and-effect answer. Yet where did he get the “stuff” to create all that there is? It could not have come from himself, as that would place him in our universe of time, space, and matter. Then we would just be looking for the really real God. The same is true if the “stuff” was outside himself. All that there is must have come from nothing as a rational and philosophical necessity. All other options are formally absurd. While creation out of nothing is not formally absurd, it is a great mystery or paradox.
2. Trinity: We believe in one God who eternally exists in three persons: the Father, the Son, and the Holy Spirit. This would only be a formal contradiction if we said we believed that God was three Gods and one God or if we said we believed he was three persons and one person. But to say that the Trinity is one God in three persons is not a formal contradiction, but a mystery.
3. Hypostatic Union: We believe that the second person of the Trinity, Jesus Christ, is fully God and fully man (at least since the time that he became man). We don’t believe that he is fifty percent God and fifty percent man, or even ninety/ten. Christ is everything that God is and has eternally, even in the incarnation, shared in the full divinity of the one God, yet he is everything that man is forevermore. Whereas the Trinity is one nature with three persons, Christ is one person with two natures. This is indeed a mystery, but has no earmarks of a formal contradiction.
4. Scripture: We believe the Bible is fully inspired of God, yet fully written by man. God did not put the writers of Scripture in a trance and direct their hand in the writing of Scripture (often referred to as “mechanical dictation”), but he fully utilized their personality, circumstances, writing style, and mood in producing the Scriptures. Another way to put it is that the Scriptures are the product of the will of God and the will of man. Mystery? Yes. Contradiction? No.
5. Human Responsibility and Divine Sovereignty: God is sovereign over the entire world, bringing about his will in everything. He does as he pleases in heaven and on earth. There is not a maverick molecule in all the universe. He even sovereignly predestined people to salvation before they were born, while passing over all others. Yet man is fully responsible for all his actions. There will be a judgment of the unrighteous one day in which God will hold people responsible for their rejection of Christ. How could there be a judgment if people were doing only what they were predestined to do? I don’t know. But I do know that they are truly responsible for their actions and rejection of God. This is a mystery beyond any human ability to solve, yet not a contradiction.
Are there more than these? Most certainly. But in theology, these are the biggies. These are the big pieces of our puzzle that are missing. Why are they missing? I don’t know. I just know they are. God chose not to tell us. I will ask him when I get there. Maybe he will tell us why. Maybe not. But I will try to trust him until then. I can’t really judge him for not giving me enough intel about the happenings here on earth or how he does things. Nor can I cross my arms and pout, expressing that I have no obligation to believe him about these things until he explains them.
Don’t get me wrong. There is nothing wrong with trying to solve these, and I think everyone needs to get into the ring and wrestle with these issues until they are beaten, bloody, and bruised. But church history has seen that whenever these are “solved,” heresy or serious aberration is always the result. Unfortunately, many continue to opt not to let these mysteries remain. Often with good intentions, Christians have found “solutions.” But these “solutions” normally have to distort God’s revelation to do so. Preferring a settled logical system, many find pieces of another puzzle and force it to fit. The result is an obscured and inaccurate, sometimes even damnable, view of God.
Where God has left the puzzle pieces out, so should we. He knows what he is doing. Let’s just thank him for the pieces we do have and worship, for now, in the white mysterious area. Hand firmly over mouth is a good theological posture sometimes.
Let’s see if I can get you a verse here . . . Got it!
“The secret things [missing puzzle pieces] belong to the Lord, but the things revealed [present puzzle pieces] belong to us and our children forever.”
Oh, and one more (my default NT go-to verse in these matters):
1 Cor. 13:12
For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.
If you are not comfortable with some mystery, you are in the wrong faith.
