are you sure? http://www.merriam-webster.com/dictionary/anti ANTI: one that is opposed so we already know what christ means so if you put the word together against-christ. dnt know where your getting your info from.
Of course I'm wrong if you use the dictionary to define antichrish. What I'm trying to tell you is that the correct translation is instead of Christ. Maybe they thought that it made more sense in context with the rest of the translations. But, never the less, time and time again they translated the word for instead into anti. Which is a close relative, but not the same. I really don't know that it makes any difference anyway. Which is prolly their reason. It's just something that you should be aware of. -
