"The English word sin is derived from the German term Sunde, which carries the connotation of sundering or dividing. The Greek word diabolos, from which we get our word devil, the evil one, basically means “scatterer”. In the Book of Genesis, the original sin – incited by the serpent – amounts to a sundering of the human relationship to God (expulsion from the Garden) and a radical division and scapegoating among creatures. Separation, suspicion, mutual hatred, blaming – all are signs that the scattering power of sin is let loose.
God, on the other hand, gathers. The history of Israel is the story of God’s gathering of his people into one through the power of his covenant. It is the story of Israel’s hope for unity, a hope kept alive through the suffering of periodic separation, of division, and even exile because of their infidelity to that covenant. All of it is God’s narrative, the unfolding of his plan for Israel and, through Israel, all of humanity. In the sending of his Son, God gives definitive expression of his power of gathering."
