The narrative introduces a new preacher of the faith, Apollos (we hear about him in Paul’s letters). He is said to be a scripture scholar but hadn’t received the Holy Spirit, yet. He preaches Jesus as Messiah. No matter who the preacher is and what methods that person uses, we must remember that there is only one Gospel of Jesus Christ. Everyone needs to have a Bible and read it, and also a Catechism of the Catholic Church which, based on Sacred Scripture and Sacred Tradition, lays out the deposit of faith.
