The Old Testament is the basics, but what is revolutionary and true about the other one?
It is the Christian notion of “Agape” - the idea of the Universe being conceived in heavenly love.
Which is not any sort of love.
The love the Bible speaks of is one that holds the Universe together and directs Man towards the ultimate of his goals:
True freedom.
A core of Christianity is this:
Man has freedom, unlike animals, because God's utmost expression of love for his creation is Man. Man is created as an image of God “Imago Dei” - in the face of God (in Latin) - meaning Man is to be seen as the gardener of a paradise created by God.
Pico della Mirandola clarified this cornerstone of Christian faith in a beautiful fashion and from his interpretation of scripture Man has found the inspiration and courage of climbing to peaks unknown to his age.
Christianity is Chivalrous. Islam is a political concept with no spiritual component.
I work with some Iraqis, and they don’t contemplate the afterlife. All of their energy is here and now, survival, a DNA marker of their Bedouin ancestry.
Hinduism and Buddism are chivalrous.
Come to think of it, every religion is still chivalrous, after all the Crusades. Except one.
