mormon God is not eternal.

[Jesus.defender]

God the father has not always been God the father. 

 

"God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! That is the great secret. ...I am going to tell you how God came to be God. We have imagined and supposed that God was God from all eternity. I will refute that idea, and take away the veil,... It is the first principle of the gospel to know for a certainty the character of God, ...and that He was once a man like us; yea, that God himself, the Father of us all, dwelt on an earth, the same as Jesus Christ Himself did; ...you have got to learn how to be gods yourselves, and to be kings and priests to God, the same as all gods have done before you, namely, by going from one small degree to another,... from exaltation to exaltation, until you attain to the resurrection of the dead, and are able to dwell in everlasting burnings. and to sit in glory, as do those who sit enthroned in everlasting power" (History of the Church, Vol. 6, Ch. 14, p. 305-6).

  "It appears ridiculous to the world, under their darkened and erroneous traditions, that God has once been a finite being" (Deseret News, Nov. 16, 1859, p. 290).

   "Our father in heaven, according to the Prophet, had a father, and since there has been a condition of this kind through all eternity, each Father had a Father" (Doctrines of Salvation, 2:47).

"I know that God is a being with body, parts and passions...Man was born of woman; Christ, the Savior, was born of woman; and God, the Father was born of woman" (Deseret News, Church News, Sept. 19, 1936, p. 2).

 "The Father is a glorified, perfected, resurrected, exalted man who worked out his salvation by obedience to the same laws he has given to us so that we may do the same" (A New Witness for the Articles of Faith, p. 64)

Joseph Smith: "I will preach on the plurality of Gods. I have selected this text for that express purpose. I wish to declare I have always and in all congregations when I have preached on the subject of the Deity, it has been the plurality of Gods. It has been preached by the Elders for fifteen years."

Joseph Smith: "The head God organized the heavens and the earth. I defy all the world to refute me. In the beginning the heads of the Gods organized the heavens and the earth."

Bruce McConkie states: "Three separate personages---Father, Son, and Holy Ghost---comprise the Godhead…As each of these persons is a God, it is evident from this standpoint alone, that a plurality of Gods exists. To us…these three are the only Gods we worship" (Mormon Doctrine, p.576-7).
