Chalice Congregation formed in 2000 after the reunion of two previously separate UU groups. The Unitarian Universalist Inland North County Fellowship, UUINCF, was founded in 1984. In 1989, a number of members voted to break off, forming Chalice Church. The reasons for the split were several and reflected a number of issues common to growing UU congregations.

By 1999, it was apparent that both UUINCF and Chalice Church would benefit from reuniting. The two congregations voted to merge with a new name. Chalice Unitarian Universalist Congregation was officially formed on January 1, 2000, with a charter signed by 115 members.

The congregation called our first settled minister, Rev. Margo McKenna, in 2001. Our second settled minister, Rev. Sharon Wylie, was called in 2012.
