'Homosexuality and all it's derivatives USED to be considered a mental illness', The DSM III categorized it as a mental illness. The true reality of it is that it is sin. It can also be overcome.

Look at I Cor 6:9-11, " Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were [c]sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.

As you said, homosexuality was around in the Roman empire as well. People involved in that sin, as well as many other sins, repented of those sins and believed in the Messiah and were saved. That salvation is available to all who repent and put their belief in Jesus the Messiah.
