The New York Times reports that Bishop Andrew Smith has authorized the blessing of same-sex unions in his diocese. However, clergy there still are forbidden to preside at civil union ceremonies. In other words, there is a clear separation of Church and State being invoked in the case of same-sex couples: the legal contract is the business of the State, while the blessing of the relationship is the appropriate role for the Church. No such distinction is being enforced in the Diocese of Connecticut with respect to heterosexual marriage.
This has been my own stance as a priest: I will bless monogamous, life-long relationships of fidelity and mutuality but I will not sign a marriage license. This isn't a particularly courageous stance on my part, as I serve a largely gay and lesbian congregation whose members do not enjoy access to the civil institution of marriage. Unlike some congregations, we are not a "wedding factory" dependent upon the revenue provided by renting out our priest and sanctuary to qualified customers. So, this has been an easy step for me to take.
I'd be curious to hear how others feel about this issue. What are the respective roles of Church and State with respect to marriage? Are civil and sacramental marriage the same thing? Does it make a difference whether the couple is gay or straight?
