Causes of homosexuality - Biblical explanation

The Bible, being the most comprehensive transcendent moral authority, abundantly deals with human nature and behavior and consistently manifests that the nature of man has not changed since the Fall. So the Bible is certainly the preeminent authoritative source when it comes to providing a framework when determining the causes of homosexuality. Man is shown to have been created as a perfectly made being (Gn. 1:31) - yet not as a robot - but as a being designed to be able to make choices, which thereby allowed him to distort his perfection. God from the beginning also joined male and female in life-long marriage, and placed a priority on the family, and provided laws, as needed, for its health and preservation and that of society, while aberrations result from failure to abide by them.
