The men of Sodom were exceedingly wicked
and sinful against the Lord.
–Genesis 13:13 (NKJV)–

The outcry against Sodom and Gomorrah is great,
and because their sin is very grave.
–Genesis 18:20 (NKJV)–

You shall not lie with a male as with a woman.
It is an abomination.
–Leviticus 18:22 (NKJV)–

Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.
–1 Corinthians 6:9-11 (NKJV)–

Keep that which is committed to thy trust,
avoiding profane and vain babblings,
and oppositions of science falsely so called: 
which some professing have erred concerning the faith.
–1 Timothy 6:20-21 (KJV)–

God also gave them up to uncleanness, in the lusts of their hearts, to dishonor their bodies among themselves, who exchanged the truth of God for the lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen. For this reason God gave them up to vile passions. For even their women exchanged the natural use for what is against nature. Likewise also the men, leaving the natural use of the woman, burned in their lust for one another, men with men committing what is shameful, and receiving in themselves the penalty of their error which was due. And even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things which are not fitting.
–Romans 1:24-28 (NKJV)–

Blessed is the man
Who walks not in the counsel of the ungodly,
Nor stands in the path of sinners,
Nor sits in the seat of the scornful.
–Psalm 1:1 (NKJV)–

From the standpoints of individual health, public health and social order, participating in homosexual activity could be viewed as dangerous to society and incompatible with full health.”

—. “Homosexual Molestation of Children/Sexual Interaction of Teacher and Pupil.” Psychological Reports 57, no. 3 (1985): 1227-1236. Those who practice homosexual acts are at least 12 times more apt to molest a child sexually, and with suitable corrections for bisexuals (who molest both genders), probably at least 16 times more apt to molest a child. A review of recorded cases of teacher-pupil sexual interaction indicated that of the 30 instances detailed in the literature, 24 (80 percent) involved homosexual acts. It appears that teachers who practice homosexual acts are between 90 to 100 times more apt to involve themselves sexually with pupils than teachers who confine themselves to heterosexual acts.
