If our position is unpopular, doesn’t that suggest we may be wrong?
No, I don't believe so — and certainly not by necessity. To judge by numbers is a dangerous game. For example, most people in the world reject that Jesus is God. However, that alone means nothing — it doesn't mean they're right, just because they're in majority. In this sense, we can say that to believe that Jesus is God is unpopular, and where I live it's extremely unpopular. Less than 1% of the population here in Japan identify as Christian.
Or to take a different example, most Christians believe in some way or another that Holy Baptism is something we do for ourselves or for God, but that's also wrong, for it is something God does for us; it's God grace for us. He has graciously given us Baptism for our comfort. So, just because this understanding is unpopular in the world of Christendom doesn't automatically mean it's false. Nowhere in Scriptures does it say anything to the effect of that
"Baptism is our public declaration of faith", which is very commonly expressed in our time. Rather, the Bible says things like:
"Whoever believes and is baptised will be saved, but whoever does not believe will be condemned." And:
"Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ." And:
"Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit."
So, whatever it may be, we always go with the plain reading of God's Word, unless there's something in the text that suggests that it should be taken figurately. This is what it means to be Sola Scriptura. I wrote a short article about it here if you're interested in understanding this in a bit more detail:
Exegesis | THE REJECTED STONE
Oh, and when I say we are few in numbers and that our position is unpopular, you have to remember that the Orthodox Lutheran body is still a very large Christian body in the world. The International Lutheran Council alone has 7.15 million members, and there are other councils and synods scattered around the world. But let us not be guided by numbers that are unreliable and changeable, but God's Word, which is reliable and unchangeable.
Can you please explain that last paragraph further?
Sure. The whole Christian Church confesses a belief in that God is one, in the person of the Father, the Son, and the Holy Spirit, and that the fullness of God dwells in Christ bodily, so Jesus is God in flesh; 100% God and 100% man. Not 50/50. Not a demi-god. But completely God and completely man. So, what is infinite is somehow supernaturally contained in what is finite. But exactly how this is possible scientifically or logically speaking is a holy mystery, that we accept through faith. We believe it because it is the truth that God has spoken and showed us in His Son. This is to say, God is too great for us to comprehend in His fullness, but He has graciously made a way for us to see and believe in Him, in Jesus Christ, our Lord and Saviour. So we recognise the profound miracle of Christ and believe in Him with childlike faith. Again, the Church has always recognised God as a holy mystery.
Now, the Lutheran Church, and to some extent, the Eastern and Oriental Orthodox, recognise not only God as a holy mystery, but also His works. The Roman Catholic, Anglican, and Reformed, however, have a tendency to claim that God is a mystery, but His miraculous works are not. I believe this to be wrong and arbitrary, and I think this is a mark of Lutheran orthodoxy — that when the Bible presents us with a paradox, we accept it as a holy mystery, knowing that what seems impossible to us is not impossible to God.
Let me give you a practical example of this using two opposing Reformed doctrines, and contrast it with the Lutheran system:
Calvinists rightly claim that salvation is entirely from God, but wrongly that damnation is also from God (either actively or passively). Arminians, on the other hand, wrongly attribute salvation to man (not as a work, but as a decision), but rightly say that damnation is entirely from man. Both Calvinists and Arminians claim reason or logic on their side, but both parties compromise on the Bible, which says that salvation is entirely from God, and that damnation is entirely from man, and this is what the Lutheran Church believes, teaches, and confesses, while understanding that it is a holy mystery rightly apprehended through faith alone.
So simply speaking, we believe that the holy mystery of God extends to His divine work. This is why we're not in the business of explaining how miracles occur, but focus on why they occur and what it means to us. We don't have to question the nature or works of God, for we know that whatever He says and does is true.
