It has come to recent attention that the bible explains of two "entities" under the title "God".

One is present throughout the first page and a half or so of the bible under the title "God", as "God" is the name we have translated from the original writings.

However, in addition the remaning thousand and more pages of the bible speak of a LORD God as oppose to the God mentioned in the opening.

I was curious as to what all of you, the spiritual community make of this dichotomy.

Is it a result of many different authors being responsible for the bible's creation?

or, is it so that LORD GOD and God are two very different entities? (God being the nurturing divinity and LORD GOD being the vengeful, punishing, wrathful, jealous ruler)
