Trik?ya and the Christian trinity

Hello all,

does anyone know of a scholarly text that discusses both the trik?ya doctrine and the Christian concept of trinity, and the differences and similarities between them? It doesn't have to be from a zen perspective though.

Also, I am interested in articles and books that focus on the trik?ya concept and how it was constructed during early Mah?y?na. I already have Guang Xing's The Concept of the Buddha - which is wonderful; I recommend it to anyone with an interest - and books similar to this one is what I had in mind.

Have you read anything on this subject and have a book recommendation, please, post it here. Thank you!
