There are 3 parts to the law in Leviticus, moral/ceremonial/judicial. Christians still only abid by the moral law, since the ceremonial law is said in the New Testament to have been fulfilled in Christ, and the judicial law was given specifically to the nation of Israel.
In any case, it is a myth that homosexuality is only mentioned in Levitcus.
"Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, not idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind. Nor theives, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God." (1 Corinthians 6:9-10)
So who is selectively applying passages?
