If you don't agree with your favorite preacher on the Trinity, what else was your favorite preacher wrong about? How do you have authority to decide what he is wrong about?
My favourite preacher would probably be Paul, and I uphold the authority of scripture. But since you are so obsessed with the absolute doctrinal inerrancy of all believers, I ask you again, ‘do you agree with the Papal position that Muslims worship the same god as Christians?’
You agree with St. Paul that there is a Trinity "The grace of our Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all" (2 Corinthians 13:13) .
As you are aware, the muslims intend that the object of worship is the same 'God of Abraham' as worshipped by the jews and Christians, however both muslims and jews have a wrong understanding of God's nature (unity). The Church proclaims the fullness of the Christian revelation in the Trinity, that the unity of God is expressed in the mystery of the three divine Persons as essential Christian belief.
Here is a one minute video about muslims converting to Christianity https://www.youtube.com/watch?v=QgWXoSs0GSY you can look up a longer video by Ismail Youssef on his conversion story.
Jesus didn't establish numerous conflicting denominations. Jesus established one Church. Jesus prayed that his disciples “may be one, even as you, Father, are in me and I in you, that they also may be in us, so that the world may believe that you have sent me” (Jn 17:21).
The Judeo-Chrislam Papal totalitarianism, got it.
