Here’s an article from J. Warner Wallace, the host of the Please Convince Me podcast. He starts the article by explaining the difference between objective truth claims and subjective truth claims.
As an example, we offer the proposition, “Jim’s car is a Hyundai”. Is this an objective claim or a subjective claim? It is clearly objective. My car is either a Hyundai or it is not, and my personal opinion will not change this fact. The truth is rooted in the nature of the object, the Hyundai automobile, and it is not dependent upon my subjective opinion. Now let’s examine another claim: “Hyundai’s are the coolest (hippest) cars”. This second claim is highly personal depending on what each of us considers “hip” or “cool”. Our opinion about this is rooted in each of us as subjects who hold varying opinions about “hipness” or “coolness”. See the difference? “1+1=2” is an objective truth statement; “Math is fun” is a subjective claim.
Then he asks the question: are claims about God’s existence and character objective truth claims or subjective truth claims? What about moral claims? You might be surprised what answers you get from Christians who have attended church all their lives.
But it seems to get trickier for people when they begin to move away from physical realities or math facts. Consider the following claim: “God exists”. Surprisingly, many Christian groups I work with struggle to define this statement as objective. But the existence of God is either a true reality or it is not, and our personal opinion is not going to change this reality. It is something we can either acknowledge or reject, but doing so does not change the reality of God’s existence. Does that make sense? Spiritual truth claims about the existence of God are objective, they are rooted in the object under consideration: God. He either exists or He does not; my opinion won’t change that fact.
At some point toward the end of our “Truth Test,” Brett and I will begin to post moral claims such as, “Premarital sex is morally wrong.” Now things usually get interesting as the Christians in our groups struggle to decide if there are such things as objective moral claims. Some are very uncomfortable identifying this statement as an objective truth claim. It’s one thing to say that we, as Christians, might believe this statement to be true, but some Christians hesitate to say this is a truth claim that transcends those who don’t accept our Christian values. The culture has effectively eroded our confidence in objective moral truth claims. The new cultural definition of “tolerance” obliges us to embrace all truth claims as equally valid or true. This is an important re-definition, because classic “tolerance” acknowledges disagreement and allows each person to hold an opposing view without having to embrace the other view as equally true. Classic tolerance requires us to endure and respect the people who hold opposing views, even as we resist these views themselves.
If you’d like to listen to Jim talk about this essay, I noticed that it was the topic of his opening monologue in his most recent Please Convince Me podcast. I think this post is interesting, because we just had a commenter who didn’t think that statements about God and morality were objective, but that these statements were true for the person making them. That would mean that if a person said “I believe that the Earth is flat”, then that statement would be true for that person. Or, if a person said “It’s wrong to murder people just for the fun of it”, then that statement would be true for them. I think it’s pretty clear that as Christians, we defend statements about God and statements about morality as objective statements. These statements are not just true for us, they are true, period.
