Von Balthasar, symbol and theory

I am guessing that von Balthasar made an option to return from a systematic to a more symbolic theology - much in the way perhaps that Heidegger wanted to return to the pre-Socratics. In this case, what of Lonergan? Lonergan surely is not one who would ever want to set aside systematic theology. Does that mean that von Balthasar's project is entirely foreign to him? I would think not, because for that matter Lonergan would not want to set aside the symbolic either. There is place for both. Theory is necessary but does not warm hearts. Symbolic language is not everything, but it is what warms hearts. And perhaps von Balthasar's project is part of the sensible symbolic aspect that is so much part of the incarnation.

And perhaps here Rossi de Gasperis' insistence on the sensible might tie up.
