I've asked many times for those who hold that all homosexual behavior is sinful to show how the Scripture used for that conclusion is an accurate description of what is going on today. The only answer I've received so far is that it is the clear Word of God. If anyone chooses to respond, can we start with the New Testament, please, so we don't get bogged down in holiness codes? Dueling blogs won't do it either. Your thoughts, your interpretation of what you believe God is saying.
You may not be getting many takers because this topic has been discussed to death on ALPB. Really. To death. I could link literally thousands of posts around "The Issue" (which is ultimately about scriptural interpretation, btw).
But to enter this discussion again, let's just look at one passage for now, Rom 1:26-27:
26 Διὰ τοῦτο παρέδωκεν αὐτοὺς ὁ θεὸς εἰς πάθη ἀτιμίας, αἵ τε γὰρ θήλειαι αὐτῶν μετήλλαξαν τὴν φυσικὴν χρῆσιν εἰς τὴν παρὰ φύσιν, 27 ὁμοίως τε καὶ οἱ ἄρσενες ἀφέντες τὴν φυσικὴν χρῆσιν τῆς θηλείας ἐξεκαύθησαν ἐν τῇ ὀρέξει αὐτῶν εἰς ἀλλήλους, ἄρσενες ἐν ἄρσεσιν τὴν ἀσχημοσύνην κατεργαζόμενοι καὶ τὴν ἀντιμισθίαν ἣν ἔδει τῆς πλάνης αὐτῶν ἐν ἑαυτοῖς ἀπολαμβάνοντες.Here we note that vs. 26 speaks of women giving up of "natural relations" (τὴν φυσικὴν χρῆσιν) for those "against nature" (εἰς τὴν παρὰ φύσιν). Though vs. 26 doesn't explicitly say this is women having relations with women, vs. 27 does make that clear with the particle ὁμοίως ("likewise") when it explicitly indicates that men engaged in relations with men. Further, a judgment is given on these relations that are "against nature" -- such relations are "the shameless act" (τὴν ἀσχημοσύνην) and "their error" (τῆς πλάνης αὐτῶν) for which they receive a penalty in their own bodies.
Note that no mention of the quality of their relationship is in view. Only the engaging in relations "against nature" is. And those are described as the "shameless act."
Further note that it doesn't say "against
their nature" as if such activity would be wrong only if they were truly heterosexual and then engaged in homosexual relations. Rather, it simply calls them "against nature" in general.
And also note that while the specific sin in view is idolatry (and yes, we have plenty of our own idolatries today, worshiping what is created rather than the Creator, but let's leave that obvious point aside for the moment), the description of the appropriateness of homosexual behavior in no way hinges upon whether or not they are idolaters. Rather, such relations are said to be "against nature" and the acts themselves are called "shameless," and that they are a punishment for the specific sin of (crude) idolatry but the judgment regarding such activity is not so bound.
