I first became aware of Bishop Gene Robinson while watching the documentary, "For the Bible Tells Me So." God Believes in Love addresses the same topic as the film, that is, the controversy over gay marriage, as well as whether or not gay couples should be allowed to adopt.
This book does not delve into the science in support or against the naturalness of homosexuality. That is a whole other argument that presets this debate, and for all intents and purposes Robinson treats this as secondary to the battle against the denial of basic rights to any group. He also saves a lot of time and superfluous explanation by orienting the book towards those individuals who quietly and respectfully disagree with the notion of the gay lifestyle, instead of violently protesting "Christian" mobs. Besides, anyone who is prone to writing death threats or tromping around military funerals with picket signs touting, "God hates fags" probably isn't level-headed enough to get through the text on the inside of the dust jacket anyway.
Supposing you do exhibit a basic level of rationale and do actually make it through the extremely accessible 195 pages of the book though, you will find at its core, four points:
1. Gay marriage does not change the traditional definition of marriage.
2. Homosexuality is not condemned in the Bible.
3. Gay marriage is not about "seeking approval for questionable behavior," but rather it is an important step in the social revolution against inequality imposed upon all minorities.
4. There is no evidence to suggest that a gay union is an unhealthy environment for raising children.
To the first point, it depends how far back you look. Merriam-webster.com defines "marriage" firstly as "the relationship that exists between a husband and a wife," "a similar relationship between people of the same sex" secondarily, and reserves the most ambiguous "a ceremony in which two people are married to each other" for last. However, Robinson points out the drastically different family system and marital traditions from the Old Testament and Medieval Times (polygamy, concubines, arranged marriages, women and children being viewed as subservient, etc.). He also points out that religion did not begin to play a part in marriage until the church began to assert its self-given authority around the 12th century.
The second point is probably the meatiest but, again, Robinson manages, for the most part, to support his claims. Although I resoundingly object to his assertion that "in order to interpret any passage in Scripture, we must employ the Scripture itself; the tradition of how the Church has interpreted that Scripture over the centuries; and ... our own God-given intellect and learning, up to and including how modern knowledge, science, psychology, and reason inform our understanding of the issues being addressed" - I understand where he is coming from, but this largely just sounds like an allowance of individual bias, which renders the Scripture unusable as a guideline - it would be hard to argue that the Bible's content is not set within a specific context, wherein lies the important determinants with which to understand it.
Robinson's study of the passages most infamously cited to condemn homosexuality (Leviticus 18:22 and 20:13, Genesis 19, and Judges 19) is sound, but certain other arguments, like the relativity of "normality," or when he implies that Jesus' silence on the issue of homosexuality in the gospels means he condoned it, Robinson makes himself appear to be grasping at thin air for additional support. His call for consistency in Christians' adherence to the holiness and purity codes is more than fair, and his uncovering of the "true" sins of Sodom and Gomorrah is probable and convincing. Most interesting, though, is his exposure of the liberties that were taken when translating Paul's letters in 1 Corinthians and 1 Timothy. However, this last point not only casts serious doubt on the Bible's purported condemnation of homosexuality, but also begs the question: how can anyone use a book so vulnerable to interpretative and translative discrepancies as more than an outline for any matter, but especially of morals and values?
The last two points are defended equally satisfactorily as well, although I will refrain from going into detail on them here, as the first two are definitely the more controversial and central aspects of the argument (besides, this is a review of the book, not a summary).
Some parts are a little too anecdotal and could benefit from more research, but overall Robinson has done an excellent job in assembling and communicating some very valid points. They may not serve as explicit approval of homosexuality, but at the very least invalidate the most commonly used tools of the anti-gay front. Although I was expecting Robinson's book to deal primarily with the theological side of the argument, it actually felt weighted in favor of secular concerns. This may seem like a weakness, but it actually ends up being more of an attribute because the Bible will always be subject to personal interpretation, and therefore a total consensus is virtually impossible.
Given the accessibility of his formatting, nonjudgmental tone of his writing, and (overall) strength of his argument, perhaps the biggest obstacle Bishop Gene Robinson will have to overcome in order to convince readers will be himself: will readers view Robinson's ordainment as a strong credential to speak on this subject, or will he be discredited as biased due to his sexual orientation?
