To me the Christ is the creative power of the universe which formed all life. I think I got this from the following the passage by Mary Baker Eddy, shown below, and is the reason I have always had the gut feeling that Christ is the power of goodness we need whenever a bigger picture is required, to accomplish something good. The Christ brings uplift, to do it! This is the power of God in our lives.... the Christ presence which is always available when we search for it with our whole heart!
The advent of Jesus of Nazareth marked the first century of the Christian era, but the Christ is without beginning of years or end of days. Throughout all generations both before and after the Christian era, the Christ, as the spiritual idea, — the reflection of God, — has come with some measure of power and grace to all prepared to receive Christ, Truth. Abraham, Jacob, Moses, and the prophets caught glorious glimpses of the Messiah, or Christ, which baptized these seers in the divine nature, the essence of Love. The divine image, idea, or Christ was, is, and ever will be inseparable from the divine Principle, God. Jesus referred to this unity of his spiritual identity thus: “Before Abraham was, I am;” “I and my Father are one;” “My Father is greater than I.” The one Spirit includes all identities.
