Yes, the Holy Spirit is paramount. However, let's not forget that God has appointed Human teachers for his Church as well. Those who disparage this fact are taking a lopsided view of how we receive and understand God's word.
1Co 12:28 And God has appointed in the church first apostles, second prophets, third teachers, then miracles, then gifts of healing, helping, administrating, and various kinds of tongues.
Eph 4:11 And he gave the apostles, the prophets, the evangelists, the shepherds and teachers,
Eph 4:12 to equip the saints for the work of ministry, for building up the body of Christ,
Heb 5:12 For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. . .
If I had listened to men I would be doing works for my salvation. Most men in the churches teach a blended gospel of works and grace which I call the Social/Moral gospel and it will not save anyone.
If we were left at the mercy of human teachers no one would be saved. Jesus promised a teacher and in Him we are to trust. He is called the Holy Spirit. In Him I will trust. You can trust in whoever you wish.
The scriptures CLEARLY teach that the churches of men will become apostate in the last days. If people wish they can continue to trust in them but they will wind up in Hell.
We are to compare with scriptures the teachings of men. Unless a human teacher has the Holy Spirit his/her teachings will be false. It is the Holy Spirit indwelling the child of God that allows him/her to see the truth in God's word. If a teacher does not have the Holy Spirit then they are a false teacher.
