Two thousand years ago a man came to Earth who was called the "Messiah", and who sought to reconcile God and Humanity. The religious called him the "Son of God" and the "Son of Man" and also the "New Covenant", by which the sins of all were wiped clean with his blood. Oddly enough, there are those today who call themselves his followers and him "King Jesus" while "evangelizing" to transform the world into perfect little sinless utopias - and who, by stark contrast also reject completely that which he stood for.
I have often found it strange, if not a little gory that blood is such a recurring theme in the Christian faith - and even more disappointing that it is being supplemented by fresh blood in modern times.
