Full Idea
Christianity has waged a war to the death against the higher type of man, it has excommunicated all the fundamental instincts of this type.
Gist of Idea
Christianity is at war with the higher type of man, and excommunicates his basic instincts
Source
Friedrich Nietzsche (The Anti-Christ [1889], 05)
A Reaction
It seems rather insulting to say that the finest and most dedicated altruism practised by the most admirable Christians is the expression of a 'lower' instinct.
