When I was reading some biographical notes recently about the Argentinian theologian Marcella Althaus-Reid, I was interested to note that she began her career working for the church among the poor of Buenos Aires, applying the techniques of liberation theology to the "option for the poor". Later, she applied those same techniques in slum communities in Scotland, before starting to apply the same techniques to the situation of the equally marginalized communities within the church itself, its sexual minorities.
I have never been engaged full time in this work, not worked directly with the poor, but in South Africa I did get involved as a volunteer in some of the activities of the Catholic Church Justice & Peace Commission, and attended several meetings and training workshops on the subject. A standard Scripture verse to open those meetings was the well-known words of the prophet Micah:
Do justice, love well, and walk modestly with God
-Micah 6:8
I clearly remember one major workshop at which these words were elaborated as a paradigm for the very concept of justice, as as set of three related relationships: relationships with God, relationships with others, and relationship with oneself.
The Jewish lesbian Rebeccah Alpert expands on this idea in her contribution to Robert Goss's "Take Back the Word: A Queer Reading of the Bible", and emphasises an implication to this injunction that I believe is a key to resolving the difficult choices facing us as lesbian, gay or trans people of faith - the importance of coming out.
