Robert Truelove interviews Pooyan Mehrshahi with a focus on the superiority or necessity of the received or ecclesiastical text position related to Muslim apologetics.
Evangelical apologist and critical text advocate, James White, very often warns that apologetics with Moslems is ruined by a received text position. He states this with absolute dogmatism, while giving zero proof or evidence for his contention. Instead of speaking with a tone of incredulity and rolling his eyes, he should explain the preeminence of his position. The only evidence is that he says it, so it must be true -- he's the authority.
On the other hand, we listen to Pooyan Mehrshahi explaining his position and giving actual evidence for it. I've written the same thing related to my evangelism of Moslems (here). Listen to Mehrshahi here on the preservation of scripture. He is a pastor of a Baptist church in Cheltenham, UK and has an amazing personal testimony, having grown up with Shia Islam, learning Arabic and memorizing the Quran in Iran. The biggest attack on Christianity by Islam is the corruption of the text of scripture. They, as Mehrshahi asserts, use and quote evangelicals to support their position. The right position and powerful position against Islam is the doctrine of preservation, which is the truth. I don't imagine White's (and those like him) position on the text of scripture doing anything but providing ammunition for Islam against Christianity. He hurts the cause.
Please watch the interview of Mehrshahi and then listen to Mehrshahi's sermon. They will square you away against the deceit of the position of White, whose position is just false.
