Religious experience as experiential and as explanatory

I have been forgetting the distinction between experiential and explanatory conjugates, in the study of Ratzinger / Balthasar. The distinction is tricky, especially in Lonergan's later phase, when the basic terms and relations are experiential. However, one can use experiential terms and relations in an explanatory way, and in a non-explanatory way, I suppose. How exactly do Balthasar and Ratzinger use them?
