Hi!
I looked up 'Sola Scripture' in Factbook and in topic guide and drew blanks in both places.
This was surprising because my Library does contain articles with that in the title.
Why did Logos not find these articles?
For articles to appear linked in Factbook, we have to first align the resources with the Lexham Controlled Vocabulary, the knowledge structure behind the Factbook. We haven't done that yet for these resources, in part because they have more fine-grained theological subjects (so they'll require some expansion of the LCV). They're on our list for inclusion, though.
Expanding the LCV? Don't forget that with the loss of Google Freebase I'm dead in the water for the tagging of Tannaim and Amoraim in the Talmud. And I promise to do my best not to miss an opportunity to remind you.
Orthodox Bishop Hilarion Alfeyev: "To be a theologian means to have experience of a personal encounter with God through prayer and worship."
