The divine cannot be reduced to a set of doctrines.
That is a very doctrinal statement you just made!
Barth is right to warn that Christians often try to construct a ladder of propositions to reach God, as though salvation were something we could secure by assembling the correct system. Doctrines are indispensable, but they are not God; they can never contain Him. Knowing the doctrines is not the same as knowing the living God.
This too is a very doctrinal statement you're making.
When faith collapses into doctrinal correctness, the door to God effectively closes.
The single most doctrinal statement you've made yet!
Religion becomes a matter of mastering propositions rather than receiving the Spirit. In this sense, certain strands of Protestantism drift towards a rule‑based posture: faith becomes "getting the doctrines right," and divine encounter is replaced by intellectual compliance. But the Holy Spirit is not confined to doctrinal systems. He speaks, disrupts, and calls—always exceeding the formulas meant to secure Him.
Is the Holy Spirit confined to the doctrinal system that you are here proposing - That is, the one that says that it isn't about mastering propositions?
Does that proposition count as one of the one's we aren't to master?
It is no wonder that theologians tend to sideline the Holy Spirit; He keeps overturning their systems. He is the divine otherness that refuses to be domesticated. Islam has faced a similar outcome: with the Spirit absent, religion hardens into a doctrinal structure.
Without doctrinal structure, anything goes.
Doctrines are merely truth claims. They are no different than any other truth claim except that they are theological in nature. Any and every theological truth is a doctrine, by definition, including every theological proposition you have made in this post. To say that we are not to focus on doctrine is to say that we are not to make any claims about God. It's as self-defeating as anything anyone could say or think.
The fact is that the teaching, "God exists" is a doctrine. If one desires to be saved one MUST believe that it is the truth.
The statement "He (God) is the Creator of all things and He is holy, perfect and just." is a doctrine that, if one desires to be saved, must be excepted as truth.
The teaching that, "We have, by doing evil things, rebelled against God." is a doctrine that if rejected, will condemn the unbeliever to an eternal Hell.
The claim that, "We, having rebelled against the God who gave us life, deserve death." is a doctrinal statement about the nature of God and the nature of our rebellion which must be accepted as truth or else the entire gospel itself crumbles into incoherent nonsense.
The statements, "God, being unwilling that all should perish, provided for Himself a propitiation (an atoning sacrifice) by becoming a man whom we call Jesus Christ and who is God Himself become flesh." and "Jesus, being Himself innocent of any sin, willingly bore the sins of the world and died on our behalf. Jesus rose from the dead." are the central claims of the Christian faith. Whoever rejects it as false has removed themselves from the category of "Christian".
And finally, the transparently biblical teaching of the Apostle Paul, that "If you confess with you mouth, the Lord Jesus Christ (i.e. acknowledge your need of a savior and that He is that Savior) and
believe in your heart that God raised Him from the dead, YOU WILL BE SAVED." is what distinguishes those who actually believe from those who are merely giving lip service to these doctrines.
In short, these doctrines already encompass the concern you are voicing and so your objection is self-defeating in at least two different ways.
Now, please don't ignore these points and pretend like I didn't say anything and respond by merely repeating this same stuff again as if it was never responded to.
