So..your saying jesus christ dying on the cross..and raising from the dead makes no diffeerence to christain belief if its a myth or a historic fact. If it's a myth..then christianity is a lie, but if it's a fact..then christianity is ver real. There is no in between...either jesus was divine olr he wasn't
One thing that is good to understand is that in a religious context, the word "myth" means something very different than how we tend to use it in common parlance. In common parlance, we (unfortunately, in my mind) use the word "myth" to indicate "lie or falsehood." In religion, myths are sacred stories infused with deep meaning and truths of that tradition. They teach values and ethics, hopes and dreams, relationships, and more; they teach a way of life and a worldview. The meaningfulness of a religion's mythos is not dependent on it's literal or factual truth; it stands regardless. In fact, mythos is
not intended to be taken literally in the first place, and if you're taking it literally, you're probably missing the point of the story (or at the very least, you're missing some of its depth).
All of that said, I won't claim that there aren't Christians who choose to take their mythology literally, but this approach is a relatively recent phenomena and definitely not one shared by all Christians across the globe. Christians are a diverse lot, as are members of any religious demographic. Unless you're a mythological literalist, it
doesn't make any difference if the story of Jesus is mythos or historical fact. It's lessons and inspiration stand regardless of this. Further, the sum total of the Christian religion doesn't boil down to it's mythology. The role the religion serves in its followers lives is bigger than that: there's community, there's virtuous living, there's meaningfulness.
There are others around the forums that could go into the fine points of this better than I if this topic really interests you.
