The minister, members of the governing body, and key leaders need to espouse the cause as a core goal of the congregation itself. Your efforts may go unappreciated, and the potential for becoming disheartened is high. Enlist the support of your congregation's leadership early on. Enlisting the leadership for financial support is also critical. If the board of your church takes a nickel and dime attitude toward social action initiatives, you're likely to struggle in securing the money you need to move ahead.
Many congregations fill leadership positions from the top down.
For example, the board chair is chosen first, then the vice-chair, treasurer, etc. It is common sense to select the best people for these key positions. In any church program, leadership is the key ingredient. Those in your congregation who have credibility and enjoy wide respect are your best bet. The UU church in Rochester, Minnesota, provides an excellent example of how leaders might be cultivated.
