Jesus is a big deal. Not only has part of the world measured time around his life with the less common "B.C." and "A.D." but as of 2010 there were an estimated 2.2 billion Christians. And that is the thing, the religion is centered on Jesus but is not called Jesusism. Christianity revolves around the life, teaching, death and resurrection of Jesus, but the faith is built on the foundations of "the Christ".

Not unlike the religion that revolves around the man named Siddhartha Gautama, but it called Buddhism. Buddha is a title, not a name, and it means "Awakened" or "Enlightened" one. Christ is a title, not a name, and it means "anointed" one. While Jesus is very important to the faith, Christianity is larger than the man named Jesus. Christianity is built on the foundations of the mystical Christ that was fully embodied in Jesus but the Christ spirit is not limited to the life of Jesus.

Jesus says that anyone who believes will have the Christ spirit and may even do even greater works than Jesus. The Holy Spirit is a more common name of the spirit of Christ that came down at Pentecost. Luther said that we are all to be "little Christs".

Again I say, Jesus is a big deal, but Jesus knew that what God was doing was (and is) much bigger than even him. Following Jesus is a great idea, however if the Jesus you follow is not able to bridge time, space, divisions and people, then you might be practicing Jesusism and not Christianity.
