11. Jesus Christ

11A. Do Mormons teach Jesus is the brother of Lucifer?

Yes,

"The appointment of Jesus to be the Savior of the world was contested by one of the other sons of God. He was called Lucifer, son of the morning. Haughty, ambitious, and covetous of power and glory, this spirit-brother of Jesus desperately tried to become the Savior of mankind."

Mormon Doctrine, p. 193

11B. Does the Bible teach that Jesus and Lucifer were brothers?

No,

"For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him."
Colossians 1:16

"And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ."
Ephesians 3:9

Jesus created all things (angels too) including Lucifer who was an angel before the fall.

11C. Do the Mormons teach that Jesus was born as a result of a sexual relationship between God the Father and the Virgin Mary?

Yes,

"These name-titles all signify that our Lord is the only Son of the Father in the flesh. Each of the words is to be understood literally. Only means only; Begotten means begotten; and Son means son. Christ was begotten by an Immortal Father in the same way that mortal men are begotten by mortal fathers."

Mormon Doctrine, pp. 546, 547

"God the Father, is a perfected, glorified, holy man an immortal Personage. And Christ was born into the world as the literal Son of this Holy Being; he was born in the same personal, real, and literal sense that any mortal son is born to a mortal father. There is nothing figurative about his paternity; he was begotten, conceived and born in the normal and natural course of events, for he is the Son of God, and that designation means what it says...Christ is the Son of Man, meaning that his Father (the Eternal God!) is a Holy Man."

"Christ was begotten by an Immortal Father in the same way that mortal men are begotten by mortal fathers."

Mormon Doctrine, pp. 742, 547

"The fleshly body of Jesus required a Mother as well as a Father. Therefore, the Father and Mother of Jesus, according to the flesh, must have been associated together in the capacity of Husband and Wife: hence the Virgin Mary must have been, for the time being, the lawful wife of God the Father."

The Seer 1853, pp. 158, 159 Orson Pratt.

11D. Do Mormons believe Jesus was begotten by the Holy Spirit?

No,

"If He were begotten by the Holy Ghost, then He would have called him His Father."

The Seer, p. 159 Orson Pratt

"When the virgin Mary conceived the child Jesus, the father had begotten him in his own likeness. He was not begotten by the Holy Ghost. And who was the father? He was the first of the human family...Jesus our elder brother was begotten in the flesh by the same character that was in the Garden of Eden and who is our father in heaven (Adam)."

Journal of Discourses, Vol. 1, pp. 50, 51

11E. How was Jesus conceived according to the Bible?

"Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel."
Isaiah 7:14

"Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.

Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily.

But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost."
Matthew 1:18-20

"And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God."
Luke 1:35

11F. Do Mormons teach that Jesus Became a God?

Yes,

"Jesus became a God and reached His great state of understanding through consistent effort and continuous obedience to all the Gospel truth and universal laws."

The Gospel Throughout the Ages, p. 51

11G. Did Jesus become a God or has he always been God?

"In the beginning was the Word, and the Word was with God, and the Word was God.

The same was in the beginning with God."
John 1:1, 2

"Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.

I, even I, am the LORD; and beside me there is no saviour. "
Isaiah 43:10, 11

"And Thomas answered and said unto him, My Lord and my God."
John 20:28
