Light does essential things. It reveals what is present by dispelling darkness. Moreover, it warms and vitalizes. Light isn't self-constituted. It is an emanation, or impartation, of its source.
In a number of places the Bible refers to the Christ as light. Isaiah prophesied that the people who walked in darkness would see a great light. More plainly, Jesus—speaking as the Messiah, or Christ—said, "I am come a light into the world, that whosoever believeth on me should not abide in darkness." John 12:46
Christian Science makes no division between Jesus and the Christ. But it makes an important distinction. Jesus was the human man; Christ is the divine idea he expressed. Jesus had a divinely appointed earth mission: to bear witness to Truth. He was the Way-shower, revealing to humanity the true nature of God and man.
