"The word "Christianity" is already a misunderstanding - in reality there has been only one Christian, and he died on the Cross"

This quote from Friedrich Nietzsche suggests that the term "Christianity" is a misnomer since there has actually just ever been one person who truly embodied the teachings of Christ, and he passed away on the cross (referring to Jesus). It implies that the arranged religion that bears his name has actually differed his true mentors and has actually ended up being something else completely.
