How do Christians in support of gay marriage interpret anti-gay Bible verses?
LGBT Evangelical Christians do not interpret the so called "anti-gay Bible verses" as anti-gay bible verses.Rather, they interpreted it purely in its socio-historical and religious context.They took the texts literally as a fundamentalists.*
Philo ,a first century Jew, knew that a man who is natural eunuch does not have sexual desire to a female ( Philo, On Joseph, XII. 58-60).This shows that the eunuch by birth in Matthew 19:12 means men who does not have sexual desire to a female.
Clement of Alexandria provided a complementary perspectiveabout the born eunuch, by way of quoting the Basilidian Christians with respect to the gospel verse about eunuchs (Stromata 3.1.1):
Some men by birth have a nature to turn away from women, and those who
are subject to this natural constitution do well not to marry. These,
they say, are the eunuchs by birth.
The Basilidians included those who are unfortunately castrated under eunuchs by compulsion, in opposition to eunuchs by birth.
In another context (Pedagogue 3.4.26), Clement himself warned Christian householders against entrusting their wives to eunuchs, because "even these are panders: they will neglect their duties and serve pleasure without suspicion, because of the common belief that they are not able to enjoy love. But the true eunuch is not the one not able, but the one not desiring to make love."Note that as a Christian who despised all manner of effeminacy in men, Clement was not even considering homosexual sex here. When Clement said true eunuchs did not desire to make love, he obviously had in mind sex with women.
Levitus 20:13 can only mean either of the following:
1) gay sex done by non-gay people.
2) gay sex done by gay people.
The former is clear on the text per se:
Leviticus 20:13 (NASB)
If there is a man who lies with a male as those who lie with a woman,
both of them have committed a detestable act; they shall surely be put
to death. Their bloodguiltiness is upon them.
Now the question is why would non-gay people have homosexual sex?
We have a complete answer from Romans 1:18-32.They do it because of their religion.
The religious setting we're talking about here is in the context of temple prostitution, fertility god worship. This is clearly an idolatry in the sense of worshiping false deities by homosexual sex.
Leviticus 20:13 is against homosexual sex not homosexual orientation.Romans 1:18-28 proves this:
Romans 1:18-27 (KJV)
18 For the wrath of God is revealed from heaven against all
ungodliness and unrighteousness of men, who hold the truth in
19 Because that which may be known of God is manifest in them; for God
hath shewed it unto them.
20 For the invisible things of him from the creation of the world are
clearly seen, being understood by the things that are made, even his
eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God,
neither were thankful; but became vain in their imaginations, and
their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made
like to corruptible man, and to birds, and fourfooted beasts, and
24 Wherefore God also gave them up to uncleanness through the lusts of
their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served
the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even
their women did change the natural use into that which is against
27 And likewise also the men, leaving the natural use of the woman,
burned in their lust one toward another; men with men working that
which is unseemly, and receiving in themselves that recompence of
their error which was meet.
Romans 1:18-27: The natural use of the female body and the natural use of the male body is heterosexual sex for heterosexual orientation.The sin of the Romans is the worship of creatures whose form is like birds, reptiles and even humans (Idolatry). This caused God to let them dishonor their bodies through homosexual sex.This act of worship is specifically called Temple Prostitution.
"Idol worship, such as the golden calf in the wilderness (Ex. 37), flared up again. Spurious gods of Canaan were plentiful. El was the supreme Canaanite deity, a god of uncontrolled lust and a bloody tyrant, as shown in writings found at Ras Shamra in N. Syria. His name means "strong, powerful."
Baal, son and successor of El, was "lord of heaven," a farm god of rain and storm, his name meaning "lord, possessor." His cult at Phoenicia included animal sacrifices, ritual meals, and licentious dances. Chambers catered to sacred prostitution by men and women (cf. 1 Kin. 14:23, 24; 2 Kin. 23:7).
Anath, sister-wife of Baal, also called Ashtoreth (Astarte); patroness of sex and war, was called "virgin" and "holy" but was actually a "sacred prostitute."
-The MacArthur Study Bible, Thomas Nelson, 1997, note on Judges 2:12.
This fact is also evident in the Corinthian religio-cultural reality:
1 Kings 15:12 (NLT)
He banished the male and female shrine prostitutes from the land
and got rid of all the idols his ancestors had made.
1 Kings 15:12 (KJV)
And he took away the sodomites out of the land, and removed all
the idols that his fathers had made.
1 Corinthians 6:9 (NIRV)
Don't you know that evil people will not receive
God's kingdom? ... Neither will men who are prostitutes or who commit
1 Corinthians 6:9 (NIV)
Do you not know that the wicked will not inherit the
kingdom of God? ... nor male prostitutes nor homosexual offenders
1 Corinthians 6:9 (YLT)
have ye not known that the unrighteous the reign of God shall not
inherit? be not led astray; neither whoremongers,nor idolaters, nor adulterers, nor effeminate, nor sodomites.
Fundamentalism is built on five tenets of the Christian faith, although there is much more to the movement than adherence to these tenets:
1) The Bible is literally true. Associated with this tenet is the belief that the Bible is inerrant, that is, without error and free from all contradictions.
2) The virgin birth and deity of Christ. Fundamentalists believe that Jesus was born of the virgin Mary and conceived by the Holy Spirit and that He was and is the Son of God, fully human and fully divine.
3) The substitutionary atonement of Jesus Christ on the cross. Fundamentalism teaches that salvation is obtained only through God’s grace and human faith in Christ’s crucifixion for the sins of mankind.
4) The bodily resurrection of Jesus. On the third day after His crucifixion, Jesus rose from the grave and now sits at the right hand of God the Father.
5) The authenticity of Jesus’ miracles as recorded in Scripture and the literal, pre-millennial second coming of Christ to earth.
