To reach the Secular gamers who would never play an explicitly Christian game, Minecraft needs to be subtle and non-threatening, teaching Christian values without scaring off those whose hearts have been hardened by years of anti-Christian conditioning. Still, there are clues to the Christian purpose of the game. The most obvious is the name: Minecraft Alpha. This is of course a reference to Jesus' revelation that He is the Alpha and the Omega (Rev. 22:13). Also, the only animals in the game you can kill for food are pigs. This emphasizes the New Covenant with Jesus where we can now eat delicious ham — a common ground we share with most Secularized people.
