Not so. The idea of becoming a god (deification or theosis) has a long and respectable history in Christian thought. Consider what St. Augustine (no Mormon he) wrote on the subject:
It is evident then, that He has called men gods, that are deified of His Grace, not born of His Substance. For He does justify, who is just through His own self, and not of another; and He does deify who is God through Himself, not by the partaking of another. But He that justifies does Himself deify, in that by justifying He does make sons of God. For He has given them power to become the sons of God. ( John 1:12) If we have been made sons of God, we have also been made gods: but this is the effect of Grace adopting, not of nature generating. Exposition on Psalm 50 (2)Many other early Christians (none of whom could be considered Mormons) expressed similar ideas. St. Athanasius expressed it concisely:
For the Son of God became man so that we might become God. ( Catechism: 460)
I wold not argue that Augustine, Athanasius, and the other early Christians who wrote about deification understood it exactly as Latter-day Saints do. But I would argue that there is nothing at all sinful to think that one might become a god someday.
Indeed, the Westminster Dictionary of Christian Thought goes so far as to state that deification is "the goal of every Christian":
Deification (Greek Theosis) is for orthodoxy the goal of every Christian. Man, according to the Bible, is made in the image and likeness of God...it is possible for man to become like God, to become deified, to become God by grace. This doctrine is based on many passages of both O.T. and N.T. (Psalms 82: (81) .6; 2 Peter 1:4), and it is essentially the teaching both of St. Paul, though he tends to use the language of filial adoption (Romans 8:9-17, Galatians 4:5-7) and the fourth gospel (John 17:21-23).
A good summary of deification from the LDS perspective can be found HERE.
Like most mormon doctrine, the teaching of becoming
a mormon god is perverse and bears no resemblance to
the Christian doctrine of theosis.
Please provide quotes showing Augustine, or Athanasius,
or from the Westminster Dictionary of Christian Thought,
... There is more than ONE GOD (please study the context
of PS 50 before posting that)
... That Gods breed in heaven (like mormon gods)
... That a Christian will become a god and breed to
populate his own planet
... That there is a Heavenly Mother God
It is a common mormon con-job to find unrelated facts,
string them into a necklace, and then claim they support
the mormon heresy.
Under examination, they never do.
30 At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.
Nowhere in the bible does it say that we will become gods, have our own planet and create celestial babies. If you believe that then you would have to say Jesus is a liar.
Whether we are like angels or be like God, it means we will be in the spirit form, not of the flesh.
