"Marx replaced Hegel's "Spirit" by matter and economic interests. In the same way racialism substitutes for Hegel's "Spirit" something material, the quasi-biological conception of Blood or Race. Instead of "Spirit," Blood is the self-developing essence; instead of "Spirit," Blood is the sovereign of the world, and displays itself on the Stage of History; and instead of its "Spirit," the blood of a nation determines it essential destiny.
The transubstantiation of Hegelianism into racialism or of "Spirit" into blood does not greatly alter the main tendency of Hegelianism. It only gives it a tinge of biology and of modern evolutionism.
Karl Popper
Well, no. In the Bible, blood is life. Which is why the law forbade the drinking of the blood of animals, especially those sacrificed to other gods. For Catholics and many other Christians, the drinking of the cup is the drinking of the Blood of Christ, and the life that is in him.
