God is dead. God remains dead. And we have killed him... What was holiest and most powerful of all that the world has yet owned has bled to death under our knives: who will wipe this blood1 off us? [Friedrich Nietzsche, The Gay Science, 1882, http://www.kirjasto.sci.fi/nietzsch.htm]
What Nietzsche meant by this oft-repeated statement was not that God has passed away in a literal sense, or even necessarily that God doesn't exist, but that we don't believe in God anymore, that even those of us who profess faith in God don't really believe. God is dead, then, in the sense that his existence is now irrelevant to the bulk of humanity. “And we,” he says in The Gay Science, “have killed him.” Nietzsche also believed that, even though he viewed Christian morality as nihilistic, without God humanity is left with no epistemological or moral base from which we can derive absolute beliefs.2
In Nietzsche's book The Anti-Christ, Nietzsche fights against how Christianity has become an ideology set forth by institutions like churches, instead of representing the life of Jesus. It is important, for Nietzsche, to distinguish between the religion of Christianity and the person of Jesus… “The word Christianity is already a misunderstanding- in truth, there was only one Christian, and he died on the cross,” he wrote in The Anti-Christ in 1888. Nietzsche respected that sincere and “genuine Christianity” which he considered “possible in all ages.”3 But apparently, Nietzsche never saw any form or representation of this genuine Christianity, as he wrote the following:
I call Christianity the one great curse, the one enormous and innermost perversion, the one great instinct of revenge, for which no means are too venomous, too underhand, too underground and too petty — I call it the one immortal blemish of mankind.4
The church is precisely that against which Jesus preached — and against which he taught his disciples to fight.
Christians have never put into practice the acts Jesus prescribed for them, and the impudent chatter about “justification by faith” and its unique and supreme significance is only the consequence of the church's lack of courage and will to confess the works which Jesus demanded.
In Christianity neither morality nor religion come into contact with reality at any point.
Perhaps, if Nietzsche had witnessed a true and authentic representation of the love of Messiah through those that believe in Him, he might have concluded that God was actually alive, since His goodness could actually be seen in a people.
