Mormons do not believe in the biblical teachings of the Trinity. Instead, they believe that God, Jesus Christ and the Holy Ghost are “distinct beings with distinct roles, [yet] are one in purpose.” The three beings of the Godhead are not equal in power or authority. Mormons do not worship or pray to Jesus. Instead, they pray to Heavenly Father through Jesus.
“[The LDS Church] acknowledges the Father as the ultimate object of their worship, the Son as Lord and Redeemer, and the Holy Spirit as the messenger and revealer of the Father and the Son. ..God and Jesus Christ are glorified, physical beings and that each member of the Godhead is a separate being.” (Gospel Topics: Godhead, lds.org)
Biblical Christianity teaches:
There is no way for human minds to comprehend the Trinity. God has revealed Himself to us as one God in three persons and three persons in one God. There is one divine essence or being. This one divine essence or being consists of three separate and distinct persons — Father, Son, and Holy Spirit. “God is the uncaused, all-powerful, all-knowing, merciful, gracious, eternal Spirit whose personality and attributes are manifested in the pages of the Bible.” (Kyle Butt)
