The New Testament also forbids homosexual behavior. I Corinthians 6:9-10: "Do you not know that the unrighteous will not inherit God's Kingdom? Do not be led astray; neither fornicators, nor idolaters, nor adulterers, nor catamites, nor sodomites, nor thieves, not covetous persons, nor drunkards, nor revilers, nor robbers will inherit God's kingdom."
Chapter 15 of Acts explains why Christians do not have to keep all the laws of Moses, such as not eating shellfish, etc.
