It is a spiritual work, but it is also a historical work of the times in Jesus times..and speaks to relationships...and yes to the roles, relationships of humans in society and to each other.
Our lives are physical and spiritual...and that is reality.
Our real lives Are physical and spiritual..and that is the struggle, the suffering and the joy.
We haven’t beamed up yet.
I think it’s ‘historical’ only in the sense that the actual text is old, written a long time ago.
The principles are timeless and, yes, spiritual. Material values, and the way that we view historical works, may change over time; spiritual values don’t change.
The ‘Old Testament’ contains a lot of emphasis and wisdom as to how we should live our material lives, as well as harbingers as to what spiritual life has in store.
But The ‘New Testament’ represents an evolution to emphasis upon our spiritual lives. The purpose of the New Testament is to instruct as to the fact that we can, in fact, ‘Beam Up’.
