(Book: I Don’t Have Enough FAITH to Be an ATHEIST, by Geisler and Turek, chapter 13.)
It’s time to dig into the Trinity itself, and Geisler and Turek want us to know up front that we’re most certainly not dealing with an unreasonable dogma here.
Despite what some skeptics may say, the Trinity is not illogical or against reason. Saying that there is one God and three Gods would be illogical. But saying that there is one God who has three persons is not illogical. It may be beyond reason, but it’s not against reason.
Gotta love the bit where they say the Trinity is beyond reason rather than against reason. In other words, if trinitarians contradict themselves, that doesn’t mean they’re actually wrong, it just means we’re too stupid to figure out a way to resolve the contradiction. It’s an IOU for the rationalization they’d like to be able to come up with, but can’t. And God’s the one that’s supposed to pick up the tab!
G&T are partly correct: depending on how you define “God” and “person,” it might not necessarily be illogical to say that one God can have three persons. If God is a category, or a species, or an organization, He/They/It could have any number of persons as members. There is one humanity that has many persons, one Republican party that has many persons, and so on. The illogical stuff doesn’t kick in until you start trying to claim that this is anything other than frank polytheism.
