I am beginning to think that the struggles I have with many theological thinkers is that their philosophies are humanist rather than Christian. I'm probably getting the words wrong in a technical sense, but I want to get my thoughts out before I get confused! By humanist I mean that, loosely speaking, they believe that we should all live for the greater good of humanity. Now, apart from those who clearly only live for themselves, is this not the only sane philosophy for any human being? As Christians we are gung-ho, talking about transformation of the world. Is that humanist or Christian or both? Where does the difference come in?
I think that maybe the difference is in where we see that the repository of wisdom lives. Does it live in human experience and human rationalising? Or does it live in the revelation that God gives us about himself? Of course, this opens up a whole new can of worms - does God's revelation exist outside the realm of human experience? But the difficulties in answering the second question shouldn't stop us honestly answering the first.
On another tack, I am now realising that there are people who say that animal rights are just as important as human rights - and for this reason we do not live for the greater good of humanity, but rather the greater good of all 'creation'. In other words, medical advance (such as the discovery of insulin) which leads to the saving of human lives does not justify experiments on animals. How does this fit into Christian thinking? Humanist thinking?
