"Anathema" - A Syriac exclamation meaning: "let him be excommunicated until the coming of the Lord." With these words the Jews began a severe sentence of extreme excommunication, and by the force of such words the guilty person was not only excommunicated from their midst, but already condemned to perdition.
"Anathema" - "Curse," deprivation of union with God, "excommunication," e.g., from "the Church," i.e., from a certain society of pious people.
Also: "set apart for calamity," that which is itself set apart, going away to calamity, "estranged" from God.
"Anathema" - The "avowed" spheres of human activity include participation in all iniquity of a moral, false religious, political, or violent nature. Nations to live a life of righteousness need to make a separation from the "accursed"-the deliverance, the eradication from the way of life of all that serves sinful purposes, that destroys man and the world around him.
