There is a significant and divisive debate in the Christian community over whether or not homosexuality is sinful. Many people believe that all Christians are "anti-gay," but there is really no consensus on homosexuality among Christians. Some conservative Christians are vehemently opposed to homosexuality and gay rights, believing that homosexuals should "become straight." However, some liberal Christians fully support homosexuality and gay rights, emphasizing God's love and forgiveness. Many Christians find a middle ground, believing that being attracted to the same sex is okay, but that the Bible prohibits sexual behaviour between people of the same gender. This wide range of beliefs is reflected in the differing positions of Christian churches and organizations. The United Church of Canada welcomes homosexuals into its congregations and allows its clergy to perform same-sex marriages. The official catechism of the Roman Catholic church states that homosexuals can be Catholics, but that they are called to chastity. The New York Times reported about a conservative evangelical Baptist church in Ausbury Park, New Jersey that attended the city's annual gay pride celebration, giving out water bottles. The church believes that homosexuality is a sin, but went "to show God's love" to the people there.
The debate over homosexuality in the Christian community largely centers around particular Bible verses relevant to the issue (e.g. Leviticus 18:22 and 1 Corinthians 6:9). Scholarly, contemporary translations of the Bible (such as the New International Version) support the view that homosexual behaviour is sinful, though not necessarly same-sex attraction (an important distinction). However, some Christians believe that the Bible has been misunderstood and mistranslated, arguing that the Bible means to condemn other practices such as child abuse and rape instead. This is likely a debate that will divide Christians for many years to come, with implications for the relationship between the Christian and LGBT communities. However, Christians from every standpoint should be able to agree on the importance of treating homosexuals with love and respect, as the Bible commands (Mark 12:31 and Proverbs 10:12). It is also helpful to consider that too much of an emphasis on sexuality can detract from the Bible's main message, that of the forgiveness found in Jesus Christ.
