‘Being’ is at the heart of Religious Text.
The opening command, the first of the Ten Mosaic Commandments, is a categorical statement of Ontological Presence:
‘I AM the Lord your God who brought you …out of the house of Bondage…thou shalt have no other Gods before Me.’
In Exodus, Moses asks The Presence Its name and The Presence replies: Ehyeh Asher Ehyeh.
‘I am that I am…thus you shall say to the children of Israel, I AM has sent me to you‘.
Of course, Theologians, the intellectuals of the Faith, proceeded to unwrap all this in the only way they knew how.
A reified concept of ‘Being’ was developed extensively first by medieval, later by modern Theologians, which was tagged with a host of sophisticated abstract features: Eternal, Infinite, Omnipotent, Omnipresent, Good-Being, Ground of Being, and such. A list of preferred measurements for Man’s ideal ‘God’.
It kept the language above the common riff-raff who it was thought took the Bible literally.
