The mission of the Congregational Development Commission (CDC) is to support Christian formation for people of all ages with effective programs.  The CDC supports the growth of St. Peter's membership through effective ministries, including fellowship activities, hospitality/greeting, newcomers/welcoming, and with other initiatives as may be needed, collaborating with other committees or ministries where appropriate.

The CDC meets once a month.  Members are elected at the annual meeting or appointed by the clergy. 

The CDC includes subcommittees for Adult Forums, Fellowship, and Newcomers, and also includes the leaders of Church School and Youth Fellowship.
