Two articles that pertain to the general subject of homosexuality are herein linked:

• Bonanza, Polygamy & Same Sex Marriage
• "Homosexuality"

Regarding the idea that "Corinthians" was only given for Corinth and not for anyone else is absurd. The burden of proof is on the one who asserts it to prove it. Simply making a statement is not sufficient and I would challenge those who say such to prove it.

To make the moral code of "Corinthians" limited only to the city of Corinth makes God a partial person, yet the Bible clearly tells that he is not:

Ro 2:11  "For there is no partiality with God."

Granted, there were incidentals/problems that were prevalent to a given church/person addressed in certain letters, but the reason why these problems were addressed was because they violated God's moral standard of righteousness. Now, lets present some evidences that the truth of "Corinthians" is not limited to Corinth but "every church."

1. What Paul taught in Corinthians contained the "commandments of the Lord" (1 Cor. 14:37). Why would the commandments of the Lord vary from one church to another or from one city to another?
2. The pattern for the collection had already been established to be done on the first day of the week in other churches besides Corinth, "Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also" (1 Cor. 16:1). It is the same law for different areas.
3. The scope of the message is for all:

   "To the church of God which is at Corinth, to those who are sanctified in Christ Jesus, called to be saints, with all who in every place call on the name of Jesus Christ our Lord, both theirs and ours" (1:2).
   
   Do the Corinthians call on the name of the Lord any differently than anyone else? Any saint was made a saint by the same sanctifying law. There was not one kind for Corinth and another for the churches of Galatia, but "all" in "every place" do the same thing.

4. "For this reason I have sent Timothy to you, who is my beloved and faithful son in the Lord, who will remind you of my ways in Christ, as I teach everywhere in every church" (1 Cor. 4:17; cf. 1 Cor. 7:17). 
   
   It is here stated that Paul's ways were taught "everywhere" in "every church." Paul didn't change his message or cater it to some church's desire. His true ways were true ways everywhere. The geographics didn't alter the message. The "gender" of marriage doesn't change with the geographical boundaries of man. Timothy was to teach Paul's ways because he was an apostle for Christ. But Paul's ways eliminate homosexuality as an alternative to male/female marriage. He taught against homosexuality to the church at Rome, to Corinth and to Timothy (Rom. 1:26, 27; 1 Cor. 6:9-11; 1 Tim. 1:9-11; note sodomites is grouped with murderers, fornicators, kidnappers and liars and is stated explicitly to be against "sound doctrine" which is according to "the glorious gospel"). Timothy would have taught this in Corinth and "everywhere" as Paul taught this in "every church."

"For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh" (Eph. 5:31).

"as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire" (Jude 1:7).
