The Stanford Encyclopedia of Philosophy has the entry for ‘Trinity’ by Dale Tuggy. ESSENTIAL reading if you want to understand the issues and not just mouth platitudes. plato.stanford.edu/entries/trinity/
An excellent lecture on the lost history of early universalism by Dr. Tuggy: youtube.com/watch?x-yt-cl=8 … r_embedded
There are some excellent articles on this and other trinitarian questions at this blog: trinities.org/blog/
The essays I’ve read are neither trite nor irrelevant but, of course, I have not yet read them all.
If you’re up to it, philosophically, the many serious logical problems with the purported trinity have been addressed by Bill Vallicella (MavPhil). You can start with this post, and follow the various branches (be warned that the philosophical arguments in some of the posts are very intricate, subtle, and use a specialized vocabulary. If you have any training or reading in Aristotle, you will probably not have much problem) maverickphilosopher.typepad.com/ … radox.html
