Scripture does tell us that the Holy Spirit will teach us. (John 14:26) “but the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you everything and remind you of all I have said to you.”
Note that Scripture here is saying only what it is saying. You are adding more to it and make it mean something entirely different.
Isa. 35:8, 54:13-17 - this prophecy refers to the Church as the Holy Way where sons will be taught by God and they will not err. The Church has been given the gift of infallibility when teaching about faith and morals, where her sons are taught directly by God and will not err. This gift of infallibility means that the Church is prevented from teaching error by the power of the Holy Spirit (it does not mean that Church leaders do not sin!)
Acts 9:2; 22:4; 24:14,22 - the early Church is identified as the “Way” prophesied in Isaiah 35:8 where fools will not err therein.
Matt. 10:20; Luke 12:12 - Jesus tells His apostles it is not they who speak, but the Spirit of their Father speaking through them. If the Spirit is the one speaking and leading the Church, the Church cannot err on matters of faith and morals.
Matt. 16:18 - Jesus promises the gates of Hades would never prevail against the Church. This requires that the Church teach infallibly. If the Church did not have the gift of infallibility, the gates of Hades and error would prevail. Also, since the Catholic Church was the only Church that existed up until the Reformation, those who follow the Protestant reformers call Christ a liar by saying that Hades did prevail.
Matt. 16:19 - for Jesus to give Peter and the apostles, mere human beings, the authority to bind in heaven what they bound on earth requires infallibility. This is a gift of the Holy Spirit and has nothing to do with the holiness of the person receiving the gift.
Matt. 18:17-18 - the Church (not Scripture) is the final authority on questions of the faith. This demands infallibility when teaching the faith. She must be prevented from teaching error in order to lead her members to the fullness of salvation.
Matt. 28:20 - Jesus promises that He will be with the Church always. Jesus’ presence in the Church assures infallible teaching on faith and morals. With Jesus present, we can never be deceived.
Mark 8:33 - non-Catholics sometimes use this verse to down play Peter’s authority. This does not make sense. In this verse, Jesus rebukes Peter to show the import of His Messianic role as the Savior of humanity. Moreover, at this point, Peter was not yet the Pope with the keys, and Jesus did not rebuke Peter for his teaching. Jesus rebuked Peter for his lack of understanding.
Luke 10:16 - whoever hears you, hears me. Whoever rejects you, rejects me. Jesus is very clear that the bishops of the Church speak with Christ’s infallible authority.
Luke 22:32 - Jesus prays for Peter, that his faith may not fail. Jesus’ prayer for Peter’s faith is perfectly efficacious, and this allows Peter to teach the faith without error (which means infallibly).
John 11:51-52 - some non-Catholics argue that sinners cannot have the power to teach infallibly. But in this verse, God allows Caiaphas to prophesy infallibly, even though he was evil and plotted Jesus’ death. God allows sinners to teach infallibly, just as He allows sinners to become saints. As a loving Father, He exalts His children, and is bound by His own justice to give His children a mechanism to know truth from error.
1 & 2 Peter - for example, Peter denied Christ, he was rebuked by his greatest bishop (Paul), and yet he wrote two infallible encyclicals. Further, if Peter could teach infallibly by writing, why could he not also teach infallibly by preaching? And why couldn’t his successors so teach as well?
Gen. to Deut.; Psalms; Paul - Moses and maybe Paul were murderers and David was an adulterer and murderer, but they also wrote infallibly. God uses us sinful human beings because when they respond to His grace and change their lives, we give God greater glory and His presence is made more manifest in our sinful world.
John 14:16 - Jesus promises that the Holy Spirit would be with the Church forever. The Spirit prevents the teaching of error on faith and morals. It is guaranteed because the guarantee comes from God Himself who cannot lie.
John 14:26 - Jesus promises that the Holy Spirit would teach the Church (the apostles and successors) all things regarding the faith. This means that the Church can teach us the right moral positions on such things as in vitro fertilization, cloning and other issues that are not addressed in the Bible. After all, these issues of morality are necessary for our salvation, and God would not leave such important issues to be decided by us sinners without His divine assistance.
