Paul writes in Titus 2 what he sees as sound doctrine. I would imagine any theologian would be interested in what the great apostle Paul views as sounds doctrine. The list is as provocative for what it doesn’t include as the things it does have in it. There is no mention of eschatology or the trinitarian doctrine. Instead, the passage on sound doctrine is all about relational character lived out in real life…
I am a firm believer that everyone will be surprised in the end, for better or worse. I will say this: if you are uncomfortable with mystery, the New Testament is hostile territory for you. The plain truth is that our God has not given us all the facts about everything. He leaves much room for our God-given imaginations and the joy of discovery.
It is not bad or wrong to explore or even speculate about things. It is a good exercise to try and piece it all together. Jesus affirms that we should be able to discern the signs of the times (Matt. 16:2-3). That is not the issue. The problem is that we isolate parts of Christ’s body over the ways we construct the recipe, without ever having baked the cake. I am in favour of theorizing and investigating these ideas, just not of judging others based on whether or not theyr share our viewpoint.
