Are the Christians, who think God approves of gays now when God did not approve of gays back then, delusional?

Yes. Very easy to become delusional when we are exposed to the many ungodly beliefs and practices accepted as normal by the society around us. But God's position on such issues hasn't changed in the slightest, and never will. He still condemns murder, stealing, rape, incest, fornication, adultery, homosexual acts, and all the other human activities He has identified as immoral.

GOD IS INFINITE, MEANING HE WHEN HE SAYS SOMETHING IS A SIN, IT IS A SIN FOREVER. GOD DOES NOT GO BACK AND FORTH OR HE WOULD BE FINITE.

ANYONE WHO STATES THEY ARE A CHRISTIAN AND CONDONE HOMOSEXUAL ACTS, NEVER WERE A CHRISTIAN IN THE FIRST PLACE. THEY NEED TO RETHINK WHAT THE LORD SAID AND ONE THING HE MENTIONED FROM THE HOLY BIBLE IS THIS>>>

In Jude 1:5-10, St. Jude warns us all about what will happen to the unbelievers, who revile God:

    "Now I desire to remind you, though you were once for all fully informed, that he who saved a people out of the land of Egypt, afterward destroyed those who did not believe. And the angels that did not keep their own position but left their proper dwelling have been kept by him in eternal chains in the nether gloom until the judgment of the great day; But when the archangel Michael, contending with the devil, disputed about the body of Moses, he did not presume to pronounce a reviling judgment upon him, but said, "The Lord rebuke you." But these men revile whatever they do not understand, and by those things that they know by instinct as irrational animals do, they are destroyed." just as Sodom and Gomorrah and the surrounding cities, which likewise acted immorally and indulged in unnatural lust, serve as an example by undergoing a punishment of eternal fire.Yet in like manner these men in their dreamings defile the flesh, reject authority, and revile the glorious ones.

Notice also in the above Word of God that practicing homosexuals and the lustful who do not repent before death do not get a pass.

BTW, DON'T FORGET SODOM AND GOMORRAH, THIS IS THE REASON FOR THEIR DESTRUCTION. DON'T LET ANYONE TELL YOU OTHERWISE!!!

Yes, and somewhat evil.

YES, they are very delusional and they are against God Almighty's boundaries. They are against what God Almighty decreed and the things He made forbidden, unlawful, and impure.

The Bible doesn't recognise the category "gay" but appears to portray sex between men as sinful.  Although there are clobber texts which seem to imply that, those same texts sometimes seem to imply that the survivors of child sexual abuse are damned.  Clearly very few people would accept that and there are no arguments about that issue, so whatever process leads them to that conclusion needs also to be applied to the absurd claim that homosexual acts are sinful in contexts where heterosexual ones aren't.

It doesn't matter what God approves or doesn't approve. We aren't Jewish. Christians are commanded to accept all, just as we have been accepted. If God decides to reject, it's not going to be because my disobedience, it will be because of a decision God made. 

God clearly tells us that he does not change, what he said was bad before is still bad today. Malachi 3:6 For I am Jehovah; I do not change. Titus 1:2 God cannot lie

Some clergymen argue in favor of homosexuality, claiming that Jesus never spoke against it.

But is that really so? Jesus Christ declared that God’s Word is truth. John 17:17

That means that he endorsed God’s view of homosexuality as described at Leviticus 18:22, which reads: “You must not lie down with a male the same as you lie down with a woman. It is a detestable thing.”

 Moreover, Jesus listed fornication and adultery among the wicked things that issue forth from within and defile a man. Mark 7:21-23

 The Greek word for fornication is a broader term than that for adultery. It describes all forms of sexual relations outside lawful marriage, including homosexuality. Jude 7

 Jesus Christ also warned his followers not to tolerate any professed Christian teacher who minimizes the seriousness of fornication.

No Christian approves of a homosexual lifestyle. The Lord Himself outright condemns it. It was also for this very reason that the Lord destroyed the two cities of Sodom and Gomorrah as the places were full of them.

Why would any Christian condone a homosexual lifestyle????? 

Never mind what Christians think about Homosexuality, what matters is what the Lord Himself has to say on the matter.

If you have any barbs or snide remarks on this issue, take it up with thee Lord and don't worry about what Christians think or say.

Homosexuality is an abomination before the Lord and that cannot be argued or defended.

Apparently the disciples think God's opinion did not change on this matter. That one seems to be behind the times.
