Why is Lord, God, and He sometimes capitalized in the Bible and sometimes not? It would seem to me that these should always be in caps.
Because these are different names for God, and they come out of different traditions. As I said last month, the Hebrew Scriptures (the Old Testament) are the result of at least 4 different traditions being merged together. In Genesis 1 the Hebrew word for God is Elohim, in pre-Hebrew “council of the Gods.” That is one tradition. There is a second tradition in Genesis 2:4b. The name for God is Yahweh Elohim, LORD God. A third tradition can be found in Genesis 4:1 where the name for God becomes simply Yahweh, “LORD.”
The fourth tradition is found in Deuteronomy where the name for God becomes Yahweh sholem Elohim, “LORD our God.”
As to the pronoun issue; Genesis 1:27 refers to God being both male and female as well as God being plural. I ask you which pronoun should we use? As to capitalization, do we really want to put an emphasis on the gender of God? I believe that God is beyond being bound to gender or being put in a box.
