Thanks to the folk who have visited this blog and also to those who have left some very nice comments. Cheers! I have a book of these now available. It’s called Theologygrams. As you can imagine, the title took a while. It is published by DLT and can be bought from their website or from amazon.
Apologies if this breaks blogging etiquette by not really being a diagram. On the other hand, feel free to add contributions.
