Well, I don't reduce people to their sexual attractions as if that's what identifies them as a person anyway. They're simply terms that describe one facet of humanity but they're hardly "redundant" as such. On one level I identify as heterosexual as I'm exclusively attracted to women so on that score it's an apt term to use. In other areas it would be entirely irrelevant.
There almost isn't an issue I have not long since studied out in Scripture and or continue to, simply out of my endless curiosity with how "things of God" work, as depicted in Scripture.
I am just as well versed in the various sciences of men - especially in Behavioral Science, as it has been a life-long fascination of mine.
I continue to find though, that Scripture needs no help from the findings of secular science.
I continue to find that...
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen. 11:2 For by it the elders obtained a good report. 11:3 Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
And how that...
11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
In this, the OP's topic is no different a fascination as a study, as its actual issue is nothing new in so old a collection of Books as Genesis through Revelation...
And what I have found is that Scripture "identifies" people as either lost or saved, as either sinner or saint, as either in the flesh, or in the Spirit - in short, as either being in Adam, or as being in Christ.
All else is said by Scripture to result, or manifest from, the one or the other of those two "identities."
In this regard, the Believer, regardless of his "temptation in my flesh" (as the Apostle Paul put that) is to view him or herself and other Believers, neither through the lens of his or her Behaviour, nor through the lens of its lack thereof, rather, through the lens that Scripture asserts is to be the Believer's lens: the lens of the Identity given him or her, IN Christ.
Case in point, one aspect of the issue at issue for Paul in his addressing of Peter and company as described in Galatians 2, was this issue of Identity.
Of Peter and company's unbecoming conduct or Behaviour towards those Gentiles there, as if the Law had not only proven Peter and company "sinners of the Gentiles...also" but as if the finished work or Behavior of Christ alone, had not had to be the case on both their behalf, and in each their stead.
In this "homosexuality" is no different an issue as a temptation some Believers struggle withn in contrast to their Identity in Christ, than that of the temptation just as often experienced by the "heterosexual" against his or her Identity in Christ.
In fact, in the gospels, where Christ is depicted saying and doing things meant to bring the issue of the flesh to even greater light, He is depicted as having noted things along that line, like the following...
Matthew 5:27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery: 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
That having been an extension of, and towards the following...
Romans 5:20 Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound: 5:21 That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
As on the following, example of those two issues...
Romans 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet. 7:8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead. 7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died. 7:10 And the commandment, which was ordained to life, I found to be unto death. 7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me. 7:12 Wherefore the law is holy, and the commandment holy, and just, and good. 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful. 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
7:24 O wretched man that I am! who shall deliver me from the body of this death? 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
On this, your supposedly "accredited science" has nothing to contribute to that, other than proving itself each time, its being nothing more than more of the same old, same old of Genesis 3's infamous "Yea, hath God said?"
You assert you are a Believer.
Well then, here is your owner's manual to ALL issues...
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 3:17 That the man of God may be perfect, throughly furnished unto all good works.
All else, is anything but that.
At least for the Believer.
Isaiah 8:19 And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead? 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
Not mad at you, mind you - Romans 5:6-8.
Just that it is time you stand by the Book you assert you hold to the Truth of...alone.
Matthew 4:1 Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. 4:2 And when he had fasted forty days and forty nights, he was afterward an hungred. 4:3 And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread. 4:4 But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
