The causes of homosexuality are attributable to man's sinful nature, nurture and environment, and personal choice. However, the importance of each factor is an issue that is debated. Those from the most liberal school usually assume a philosophy of determinism […] This belief is then used to justify acting it out.

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 for determining the causes of homosexuality. Man is shown to have been created as a perfectly made being […] but as a being designed to be able to make choices, which thereby allowed him to distort his perfection.

The prohibition of it is given along with sexual relations with animals […] and is clearly condemned wherever it is manifestly dealt with.
