This class took a deeper look at typology. I personally felt like I did a poor job communicating. But the response was good and we had a good discussion. Video will be uploaded tomorrow.
The intricacies of typology are still beyond me. I'm growing in the department and learning how to refine my eye. I think in a very real sense proper typology is essential to avoid allegory. A well laid out and valid typology that encompasses large Old Testament passages can keep you from taking the small details and running wild with them.
In a way then, well defined typology works the same way that a stringent historical-grammatical method works. It helps reduce the plurality of possible interpretations down to the smallest number possible. These two tools can be very helpful and re-reading Goldsworthy on this section was extremely beneficial to me and my study.
