The '''sexual orientation theory''' asserts that a person's
[[sexual preferences ]] are immutable and should therefore be accepted by society, <ref> [http://www.abidingtruth.com/pfrc/books/sevensteps/Chapter3/index.html Seven Steps to Recruit-Proof Your Child] </ref> as theorized by some developmental psychologists and advocated by many social advocates and partisans.
Many social advocates assert that unknown biological factors are responsible for sexual orientation. Thus, they argue that is by no means a matter of [[Homosexuality and Choice|choice]], and that it is pointless to try to change one's orientation. Some go so far as to say that the attempt would cause harm, so
[[mental health ]] professionals must not offer assistance even if asked.
[[sexual preference ]] refers to a person's preferred mode of sexual activity, fantasy or desire.
Advocates of [[homosexuality]] frequently argue that sexual orientation is fixed at birth, i.e. one is "born that way". This forms the basis of an argument that homosexuality is not a matter of choice, and thus should not be criticized. One may as well criticize a person for having blond hair, or dark brown skin.
However, in both of these instances, it could as well be argued that these are the result of personal experience and development: for instance alcoholism is seldom found in infants but develops as individuals gain experience of alcohol and see it as a solution to their problems or a route to happiness.
Some Bible passages suggest that the normal, God-given ''orientation'' for human beings is [[heterosexuality]]. Jesus taught,
*"Did you not read that He made them at the beginning of creation, male and female, did He not?
*"And it said, because of this a man leaves his father and his mother and clings to his wife and they become both one flesh.
*"From then on they are not two, except one body. What God has thus united, a human being does not separate." (Matt. 19:4-6)
Nonetheless, no explicit condemnation of homosexuality is ever ascribed to the
Son of God: all these are found in the Old Testament and the Epistles.
