In the idea of eternal progress, many writers have said that Gregory of Nyssa, writing in the fifth century, made an original contribution to the history of thinking. And it has an implication for us. If this is our sense of the human journey and of our journey to God, and if this is our image of God or this is how we can begin to think about God, it has a big implication for the way we live in fact, for our idea of community, of church, and human progress in general, that there is eternal progress. And the good side of it is that there is no limit to our progress towards God, we are never satisfied. So gradual enlightenment could be understood not as being slow, but as being infinite. Our experience of the journey may be gradual today but sudden tomorrow or gradual this morning and sudden this afternoon. So, gradual and sudden really refer to different ways of perception, different ways in which we are interacting with the evolution, with the journey itself.
