There has been a Christian congregation for this church close to this site since 1833. Not this building (that came in the 1860s), and not called The Uniting Church (that came in 1977).
With the homeless man camped on their doorstep, I think the words on the plaque are significant:
Believing that change is always possible, we participate in moves towards justice, peace and development for all people every where.
With open heart and mind, and in ways tried and untried, we commit ourselves to this task, believing that 'where the spirit of the Lord is, there is Liberty'.
