The ESV does not capitalize deity pronouns mainly for two reasons: (1) The capitalization of deity pronouns in the Bible is a recent innovation that began less than fifty years ago. For example, the KJV Bible and its later revisions (except for the NKJV) did not capitalize deity pronouns. Given the legacy of the KJV, the ESV translation thought that this would be best. (2) Also, the original Bible manuscripts in Greek and Hebrew do not capitalize deity pronouns. Hebrew manuscripts do not have capital letters. In Greek manuscripts, the letters are all either capital or lower case.
