How can I use Logos to find the origin of Holy Saturday?
You should indicate what you have tried.
I can only restate that you see what Factbook says about it and use its Search (which you should switch from ALL to Books) together with its other tools.
Christian, the answer to any question of the form "How can I use Logos to find XXXX" is nearly always:
Do this, and you will be rewarded. If your search doesn't find enough, try using synonyms for some of the search terms.
In the example you're inquiring about here, I would separate "origin" and "Holy Saturday" (in quotes) as the two main search terms. I usually ignore small connecting words and just search for the key words.
Furthermore, the word "origin" has a common synonym "development" when it comes to origin of faith practices and doctrines.
So for this example, I would search for: (origin OR development) NEAR "holy saturday"
Hopefully the steps above will help you generalize this to many of the sorts of questions you ask about here, so that you can do these searches yourself instead of continually asking again where the answers will be so similar (just plug in different search terms). I know you struggle with short-term memory issues, but perhaps you could print out a cheat sheet for yourself with these instructions.
Start with Wikiipedia as it is your friend in finding synonyms, references etc. Secondly, it will not be productive to look for Holy Saturday as it did not develop in isolation but is rather an element of Paschal Triduum ... Maundy Thursday evening through Easter which is a single celebration in Catholic (and other churches). The Paschal Triduum falls between the liturgical seasons of Lent and Easter. Note: the liturgical churches that don't use the Triddum season model use the Holy Week model - but Holy Saturday still has no independent development. Logos is rather weak in all things liturgical year so if you want more than the dictionary entries, let me know.
This is a decent starting point for the whole season Farwell, James. This Is the Night: Suffering, Salvation, and the Liturgies of Holy Week. London; New York: T&T Clark, 2005.
Thanks everyone. I printed a cheat sheat for me.
Here's a book I just stumbled upon that I didn't have in my Library, but which Logos sells:
