If the “Bible alone” is the “sole authority” according to protestants, then why are there THOUSANDS of denominations? Who’s right?

Let us join in prayer for the healing and conversion of Bishop Mari Mari. May he embrace the One Holy, Catholic, and Apostolic Church under the guidance of the Holy Father. Grant him the grace to renounce all heresies, especially Nestorianism, and to fully embrace the truth of Christ. We also pray for his physical and spiritual healing, that through his sufferings, he may unite with Jesus in His passion. With humility, we seek the intercession of the Theotokos, the saints, and the angels, as we offer our prayers to the Father, the Son, and the Holy Spirit. Amen. ?**
