In his recent video, David "No exegetical abilities" Bartosiewicz claims that no single church can make claim to being the true Church:
Compare and contrast with the words the Bible (in Dave's sola scriptura perspective, the sole formally sufficient source of authority):
Simon Peter answered, "You are the Messiah, the Son of the living God." And Jesus answered him, "Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven. And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." (Matt 16:16-19 NRSV)
I am astonished that you are so quickly deserting the one who called you in the grace of Christ and are turning to a different gospel--not that there is another gospel, but there are some who are confusing you and want to pervert the gospel of Christ. But even if we or an angel from heaven should proclaim to you a gospel contrary to what we proclaimed to you, let that one be accursed! As we have said before, so now I repeat, if anyone proclaims to you a gospel contrary to what you received, let that one be accursed! (Gal 1:6-9 NRSV)
There is one body and one Spirit, just as you were called to the one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all. (Eph 4:4-6 NRSV)
He also sprouts the time-worn arguments in favour of his Evangelical Protestant theology (e.g., nature of the atonement and justification). To see how biblically bankrupt his arguments truly are, see, for instance, Why Latter-day Saints cannot believe Evangelical Protestantism is True: A Response to Dave Bartosiewicz. Dave has been refuted time and time again on these issues, so he is clearly being disingenuous as well as a preacher of a false gospel.
