Do Mormons believe that Jesus Christ is the creator of the Universe?

I assume that if something is written in the Book of Mormon, most will accept that that is what we believe.
A group of Nephites (an ancient branch of the Israelites) declared this, “O have mercy, and apply the atoning blood of Christ that we may receive forgiveness of our sins, and our hearts may be purified; for we believe in Jesus Christ, the Son of God, who CREATED heaven and earth, and all things; who shall come down among the children of men.” –Mosiah 4:2 (right out of the Book of Mormon).
There are MANY verses similar to this throughout the Book of Mormon, which is a great read if you ever have the time. I’m reading it through for the 23rd time myself.
We believe that Jesus is “the Word” that was WITH God, and the Word was God… and all things were made by him. –John 1:1-3
