Seven Baptist theologians in the UK have penned a very good piece of constructive work, and a clear articulation of Baptist ecclesiology, in this statement ‘The Courage to be Baptist: A Statement on Baptist Ecclesiology and Human Sexuality’ [pdf].
They describe the Statement as ‘a call to Baptist churches to face our present disagreements over same-sex marriage by being faithful to a Baptist way of being church’.
The full Statement, plus some supporting documentation, can be accessed via this dedicated website.
