In my opinion, it seems that the following verses emphasize the gender binary classification (i.e, Either male or only female, but mutually exclusive from each other)
Genesis 1:26-28 (NASB)
26 Then God said, “Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the [a]sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.” 27 God created man in His own image, in the image of God He created him; male and female He created them. 28 God blessed them; and God said to them, “Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the [b]sky and over every living thing that [c]moves on the earth.”
Matthew 19:4-5 (NASB)
4 And He answered and said, “Have you not read that He who created them from the beginning made them male and female, 5 and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’?
Genesis 5:2 (NASB) 2 He created them male and female, and He blessed them and named them [a]Man in the day when they were created.
Also, the lesbian, gay & bisexual, and probably those who struggle with gender dysphoria or willingly decide to be transgender but physically show either male or female genitals, but not both (i.e, not showing any sort of intersex characteristics or hermaphrodite characteristics) could be because of
selfish fleshly sinful desires associated with said sexual perversion
and/or (from a charismatic/pentecostal perspective) be under some kind evil demonic spirit that brings about desires associated with said sexual perversion
However, in regards to those showing any sort of intersex characteristics (or hermaphrodite characteristics) which would be case where "an individual has both ovarian and testicular tissue. The ovarian and testicular tissue may be separate, or the two may be combined in what is called an ovotestis. Affected individuals have sex chromosomes showing male-female mosaicism (where one individual possesses both the male XY and female XX chromosome pairs)" (Credit reference: Britannica, article at: https://www.britannica.com/science/hermaphroditism), I can only think of the following bible verses that:
Matthew 19:12 (NASB) 12 For there are eunuchs who were born that way from their mother’s womb; and there are eunuchs who were made eunuchs by men; and there are also eunuchs who made themselves eunuchs for the sake of the kingdom of heaven. He who is able to accept this, let him accept it.”
but then it seems like "eunuchs" would be a poor English translation to be associated with those who are in the Intersex (or Hermaphrodite) category.
ΚΑΤΑ ΜΑΤΘΑΙΟΝ 19:12 (1881 Westcott-Hort New Testament) 12 εισιν γαρ ευνουχοι οιτινες εκ κοιλιας μητρος εγεννηθησαν ουτως και εισιν ευνουχοι οιτινες ευνουχισθησαν υπο των ανθρωπων και εισιν ευνουχοι οιτινες ευνουχισαν εαυτους δια την βασιλειαν των ουρανων ο δυναμενος χωρειν χωρειτω
ΚΑΤΑ ΜΑΤΘΑΙΟΝ 19:12 (SBL Greek New Testament) 12 εἰσὶν γὰρ εὐνοῦχοι οἵτινες ἐκ κοιλίας μητρὸς ἐγεννήθησαν οὕτως, καὶ εἰσὶν εὐνοῦχοι οἵτινες εὐνουχίσθησαν ὑπὸ τῶν ἀνθρώπων, καὶ εἰσὶν εὐνοῦχοι οἵτινες εὐνούχισαν ἑαυτοὺς διὰ τὴν βασιλείαν τῶν οὐρανῶν. ὁ δυνάμενος χωρεῖν χωρείτω.
I do not know any Koine New Testament Greek, therefore, is there any possibility that the Koine New Testament Greek translations above would take into account people who are in the intersex (or hermaphrodite) category?
Basically, I am trying to find a biblical approach as to how Christians should approach someone who sadly and unfortunately was born into the intersex (or hermaphrodite) category. I understand that people might bring up "encouraging" verses like
Galatians 3:28 (NASB) 28 There is neither Jew nor Greek, there is neither slave nor free man, there is [a]neither male nor female; for you are all one in Christ Jesus.
Which is alright, but I'd like more insight into what the Bible has to say.
