One aspect of conservatism vs progressivism is attitudes to scripture. Many conservatives answer questions about their faith with a quote from their scripture, with the subtext that this is the authoritative word of God, Buddha, etc. In which case it's like a closed system resistant to change, after all how can we change God's revelation?
If the attitude is that the scriptures are human writings, relative to their time and cultural context, open to scholarly research and re-interpretation, then that's what I'd characterise as at the liberal end of the spectrum.
What if the hokey cokey really is what it's all about?
