you misunderstand me. The Holy Spirit has been leading the Church for 2,000 years!!
the Holy Spirit is not the author of confusion and He is not going to lead men to believe one doctrine for 1,500 years and then lead other men to believe a completely opposite doctrine since the 16th century.
we believe Jesus when He said the gates of hell would not prevail against the Church and that He would be with us ALWAYS, even to the end of the world.
was the Holy Spirit and the Word enough for the eunuch in Acts 8?
I’m not sure what relevance the eunuch is to this discussion. He was not born again - so yes, he needed help in understanding scripture and hearing the Good News about Jesus death, resurrection and being Born Again. When he heard the Word and BELIEVED, Philip baptized him. Scripture does not say specifically, but my assumption would be that he was filled with the Holy Spirit from that moment on as most Believers were filled with the HS in Acts. Otherwise, he could not easily grow his faith on his own back in Ethiopia. I suspect that when he read scripture from then on, the HS opened his heart and he understood it much more easily.
Also, note how active the Holy Spirit was in connecting someone seeking Truth with a Spirit-filled Believer that could share the Good News and get the eunuch saved.
Religion certainly did not, and could not, get the eunuch saved.
And one last time:
But when he, the Spirit of truth, comes, he will guide you into all the truth. John 16:13
It would take a theologian to misunderstand the above passage.
