At this time, I use the homily builder solely for lectionary based Bible studies. The Sermon Assistant so far does not impress me for homilies. In short, it goes against my basic understanding of a homily - the breaking open of scripture to feed the assembly. The Sermon Assistant is using artificial human intelligence to assist in a process that should be driven the Holy Spirit and prayer. However, the Sermon Assistant does have significant possibilities as a Bible study assistant - a different focus for marketing.
However, I still find the tools biased in ways that are not helpful to the ACELO churches (high Anglican, Catholic, Eastern Orthodox, high Lutheran, and Oriental Orthodox + some mainline Protestant churches).
- the liturgical calendar should be factored into the AI algorithm, as a minimum seasonally. There are a number of books providing good descriptions of the calendar that could be used to inform the AI
- quotations could be drawn from collections of quotations and selected by AI. The catalogue of such quotes should allow for user choice in very broad strokes.To be blunt quotations from a Reformed approach are rarely useful to me; Lutheran quotes may be.
- at least in my testing, Outlines tend to provide Reformed theology - again the ACELO, pietist, anabaptist perspectives are directly or indirectly of use; Reformed is not.
- in illustrations, I personally prefer to use teaching tales from religions around the world or exempla from Medieval Europe, Jewish folklore, or apocryphal stories. ... this use is outside what this tool is trying to do. So I put this feature in the "useful to some, but that some does not include me" class.
- in questions, I really need to be able to ask closed questions i.e. questions that have specific answers vs. open questions i.e. questions that encourage discussion. Most of the time the questions I am offered have reasonable quality - occasionally my topic results in rather generic questions that I wouldn't use.
- in applications, this section has possibilities, but it assumes a hermeneutical stance re:application that is foreign to me. I look for the literal meaning and one or more of the following (a) something I am to believe (b) something I am to do (c) something I am to hope for (yes - the traditional 4 senses of scripture).
All of which is to say, I think you are heading in a very useful direction - better suited to lessons than to homilies - but you need to get specific feedback from a representative sampling of denominations - Mennonite, Methodist, Presbyterian, evangelical, Stone-Campell, Catholic, Orthodox, Anglican, Lutheran (ELCA/LCMS), Orthodox, Uniting- would cover a big chunk of Christianity. The groups I listed are ones that I know enough about to be able to see how they would perceive the tools' outputs differently than I.
Edit: I should make it clear that there are Reformed authors I respect and that there are other strains of Christianity that are even less useful. But I thought the forumites would recognize the gulf between Catholicism and Calvin better than other gulfs. I mean how many of us truly understand the Waldensian/Catholic gulf?
