Because - and I may be incorrect on some of these points as the frustration level has risen:
- the Factbook for Biblical Events appears to have no coordination with either the Miracles or the Theophanies datasets
- neither Biblical Events nor Miracles appear to be documented
- Biblical Events for the deuterocanonical books are partially coded, for theophanies not coded at all, for miracles no documentation to check
I began to create a visual filter that would show me miracles (blue underline), theophanies (yellow glow) and Biblical events (red bar on the left) so that I could see at a glance what was or was not tagged by Faithlife. For my proof-of-concept, I selected a Gospel, knowing it required tedious and clunky methods:

Obviously, there should be a way to select ANY event i.e. specify the search in a single argument as is possible for Miracles and Theophanies. In addition, there is a noticeable lag between clicking in Formatting and having the menu become available . . .
