"The lack of multiple references doesn't disturb the person who has a sense of theological realism. Such a person is aware that the Bible could hardly be more explicit in its condemnation of homosexual behavior (e.g. Romans 1:26-32), but those who want to justify homosexual behavior simply dismiss the biblical texts as not relevant to today or interpret St. Paul to mean "promiscuous" sodomy although St. Paul makes no such distinctions. Even if the Bible were filled with explicit condemnations of abortion, sterilization, and contraception, the same approach would be used on such texts by those who wished to justify such behavior as compatible with biblical Christianity. Thus it is the belief of the Roman Catholic faith and of many other Christians that Jesus did not leave us with only a book subject to everyone's personal and sometimes contradictory interpretations but also established His Church as an authoritative teacher guided by the Holy Spirit. The constant teaching by the Church on a matter of faith and morals is called Tradition."
