I'd like to research where a word or topic is addressed in a lectionary. I'm hoping some of you advanced users can point me in the right direction. Here's the scenario:
Let's say I'm studying grace. I can easily search my Bible for greek:χάρις and come up with a list of references to consider. Since my church follows the Revised Common Lectionary, it would be helpful to know which (if any) of the verses containing a hit will be read during worship at some point as we work our way through the lectionary.
If I were looking for just a single reference, it ought to be easy to search for that passage within the RCL and find any instances where it occurs. But I when I try this with passages I know are included in the lectionary, I get no results. Is my search formatted incorrectly? Regardless, I can't think of a way to take the results of a previous search and use them all as the references for a new search.
I also know it's possible to create Passage Lists from multiple searches, and then merge them. If I had a Passage List containing all of the references in the lectionary, I could use an Intersection merge to find just the ones that include the word χάρις. And really, when you think about it, lectionaries aren't much more than specialized Passage Lists. It ought to be easy to perform this sort of comparison, but if there's a way, I haven't thought of it yet.
So what do you say, search gurus? If there's a method to perform this, I'd love to learn from you. And if there's not, well... in that case, I guess I need to make a request for it, don't I? 
Thanks for your thoughts!
