This doesn't only apply to who the AC is, but for every Prophecy that God inspires.....
Honestly holding to a speculation or opinion of an outcome of something that hasn't happened that isn't clear in Scripture but doubling down on it is pretty much like being a prophet.
To make an assumption for a prediction that's not clearly supported by Scripture is making a private interpretation of prophecy.
Nothing is wrong with giving opinions in guessing an outcome of a prophecy that's not clear in details.
But when we have an opinion we should say it's an opinion, and recognize that our own opinions are no stronger in being correct than another person's opinion and not worth ongoing debates over because there's no scripture evidence to prove our position. When opinions begin to create division and discord among brothers and sisters in Christ it's best to let the discussion rest.
God has given us exactly what He wants us to know in His Word and what He hasn't made clear with details leaves us with Trusting God that however it plays out it is in accordance to His Will. God doesn't keep things from us because He wants to have us in the dark. Sometimes God won't reveal everything because it moves us to exercise faith and trust in Him.
Some Prophecies are clear, and some are not and it's only when that prophecy comes will we know because God will make it clear to us that a certain Prophecy has been fulfilled.
Take for instance the prophecies of the regathering of the nation of Israel after being scattered among the nations after the destruction of the temple in 70 AD, and the nation being reborn in a day.
Nobody could have known how it would have played out until it happened in 1948 when the nation of Israel was reborn, and the partial fulfillment of the beginning of that regathering began and will ultimately be completely fulfilled in the Millennium.
God knows the end from the beginning.
We don't have to know everything because our trust in God gives us confidence that everything will result in God saying " it's all good", as He said with each day of Creation.
For us who belong to God, we know that however God fulfills His Reliable Prophetic Word it's in no way going to harm us, because God always works for the good for those who love Him.
"knowing this first, that no prophecy of Scripture is of any private interpretation"
2 Peter 1:20
May the Love of God in us move us to remain in one accord as one body in Christ
