(Book: On Guard, by William Lane Craig. Chapter 10: “Is Jesus the Only Way to God?”)
Normally I hate it when people give away the plot, but today I’m going to make an exception. I’m going to give away the plot behind the “Christian exclusivism” argument that William Lane Craig is making. When Craig says that Jesus is the only way to heaven, he’s not being as humble and pious as he’d like everyone (including himself) to think. He’s not exalting God and abasing man. The whole point of Christian exclusivism (or “particularism,” as he calls it) is to put Christians in the position of having a unique monopoly on what people are supposed to believe and how they must behave. Religious pluralism is anathema to him precisely because it allows people to believe and obey things Christians haven’t approved.
The problem with Christian exclusivism is that, from God’s perspective, there’s no reason for it. If, as the Gospel claims, God were a loving heavenly Father Who earnestly wanted all of His children to be saved, the last thing He would want to do is to tack on some arbitrary and often impossible requirements that severely limit the number of salvations. Craig expends a fair amount of effort trying to defend his exclusivist position against the obvious charge of injustice, but he can’t really explain why God ought to limit salvations in the first place. Shh, don’t tell anyone: the real reason is first and foremost to establish the dominion of Christians like himself.
