It is wrong to use the bible as justification to ban same sex unions on the whole population. I will show bible thinking from Adam to Moses to Christ as to why this application distorts truth.

(Hebrews 5:14) But solid food belongs to mature people, to those who through use have their perceptive powers trained to distinguish both right and wrong.

Because of Adam’s sin in the Garden of Eden his offspring were no longer under the law of God but of sin. Adam was in a covenant relationship with his God. By his sin, mankind was orphaned from God and his purpose. Consequently, sin cannot be charged against someone when they are not under a law covenant!! Since mankind as a whole hasn’t entered into a covenant with God, there is no condemnation for their sins. If this wasn’t so, you could never get a resurrection!!

(Romans 5:13, 14) “For until the Law sin was in the world, but sin is not charged against anyone when there is no law. Nevertheless, death ruled as king from Adam down to Moses, even over those who had not sinned after the likeness of the transgression by Adam, who bears a resemblance to him that was to come.”

The bible’s condemnation of same sex relationships was given to the nation of Israel only. It was made so by a covenant instituted through Moses. The people as a nation swore to God to uphold this law. An Israelite was bound for life to the covenant. One could never by choice escape the condemnation for a violation of the law!! This covenant never applied to the whole population. Why not?

(Exodus 24:3, 4) Then Moses came and related to the people all the words of Jehovah and all the judicial decisions, and all the people answered with one voice and said: “All the words that Jehovah has spoken we are willing to do.” Accordingly Moses wrote down all the words of Jehovah.

Some point to the flood as an example of God’s wrath against this sin. But the truth is the flood came because of materialized angels having sexual relationships with women producing a hybrid race. These beings were not in harmony with God’s purpose of a brotherhood of mankind. Consequently, God forced the materialized angels back to the spirit realm through the flood. This is why the bible speaks of the angels in “prison” and “Tartarus”. They have been prevented from materializing ever again.

(Genesis 6:2) then the sons of the [true] God began to notice the daughters of men, that they were good-looking; and they went taking wives for themselves, namely, all whom they chose.
(1 Peter 3:19, 20) In this [state] also he went his way and preached to the spirits in prison, who had once been disobedient when the patience of God was waiting in Noah’s days, while the ark was being constructed, in which a few people, that is, eight souls, were carried safely through the water.

(2 Peter 2:4) Certainly if God did not hold back from punishing the angels that sinned, but, by throwing them into Tartarus, delivered them to pits of dense darkness to be reserved for judgment.

Still some point to Sodom and Gomorrah as another example. The men of these cities were practicing rape. God answered and responded to the cries from the people who were being terrorized by them.

(Genesis 19:4) Before they could lie down, the men of the city, the men of Sodom, surrounded the house, from boy to old man, all the people in one mob.

(Genesis 19:13) For we are bringing this place to ruin, because the outcry against them has grown loud before Jehovah, so that Jehovah sent us to bring the city to ruin.

What does this mean for modern day Christians? As stated earlier, An Israelite was bound for life to the covenant. One could never by choice escape the condemnation for a violation of the law!! But the Christ instituted a new covenant. A covenant based on individual choice not a national choice. Consequently, by self-righteous zealots seeking to impose their wills and not God’s prove false to the teachings of the Christ.

The law of national choice failed in the nation of Israel. It wasn’t that the law was flawed but that the people were sinful. God proved to us it could not and would not work worldwide. Because the bible teaches us how to overcome sin and death through our own individual thoughts and actions. We willfully do this not under any compulsion.

(Romans 10:2-4) For I bear them witness that they have a zeal for God; but not according to accurate knowledge; 3 for, because of not knowing the righteousness of God but seeking to establish their own, they did not subject themselves to the righteousness of God. For Christ is the end of the Law, so that everyone exercising faith may have righteousness.

(Romans 8:3, 4) For, there being an incapability on the part of the Law, while it was weak through the flesh, God, by sending his own Son in the likeness of sinful flesh and concerning sin, condemned sin in the flesh, that the righteous requirement of the Law might be fulfilled in us who walk, not in accord with the flesh, but in accord with the spirit.

(Matthew 15:19, 20) For example, out of the heart come wicked reasonings, murders, adulteries, fornications, thieveries, false testimonies, blasphemies. These are the things defiling a man; but to take a meal with unwashed hands does not defile a man.”
