In Family Values in the Jewish Tradition, Professor J. David Bleich presents Judaism as a religion of law. He describes the family unit, "both as a social unit and as a legal institution," and how it helps to provide comfort, companionship, and stability. He discusses the role of reproduction within the family unit, artificial insemination, and the homosexual act (not the homosexual as a person). Professor Bleich concludes with a discussion of the phrase, "be fruitful and multiply." He notes that this phrase is understood as both a commandment and a blessing.
