- Muslims are less willing to translate the Koran than Christians are the Bible. This fosters more adaptation in Christian groups, thus suggesting that they might be amenable to competition with substitutes. (P. 273)
- Christians are more willing to combine religion with commercial enterprises in disseminating the Bible, again suggesting greater flexibility in competition with substitutes as different versions of the Bible can appeal to different market niches. (P. 275)
- The Christian population is wealthier overall and has more resources to devote to spreading its message. (P. 277)
- Christianity and its various denomination forms has proven adept at competing in open religious markets, while Islam's strongest manifestations are in state-supported nations. If religious freedoms are trending upward around the world, then Christianity has a leg up in succeeding. (P. 277)
- Islam has not confronted modernity and pluralism to the extent that Christianity has, and this hinders the spread of Islam in an increasingly modern and pluralistic world. (P. 278)
- Islam is the fastest growing religion tradition (as distinguished from denomination) in Europe, due to both immigration and high birth rates. Muslims comprise about 5% of the European population today, but are predicted to comprise 10% by 2020. This suggests Muslims can compete with Christians on their own turf.
- The rise of Muslim populations in Europe has led to increased persecution and restrictions--sometimes even state sponsored--on Muslims in Europe. Those on the European political right disagree religiously with Islam, while those on the political left disagree with Muslim culture. Many Christians fear Muslim competition enough to start changing the rules of the game.
- Muslims often try to use democratic methods to enact policies in line with their teachings, which suggests that Muslims are more adept at operating in pluralistic societies than the authors give credit.
