Is the Trinity Monotheistic?

Yesterday while hunting interesting blogs to add to my blog links, I came across this excellent and very civil discussion on the doctrine of the Trinity and the nature of God. Participating in the discussion are a wide range of views even including an Orthodox Jewish professor of medieval Islam and a Buddhist! It is a very long discussion, but well worth the effort. This particular doctrine is one that I have spent quite a bit of time studying during the past several years. Please check it out here.
