While each congregation has the right to ordain anyone it chooses, the Unitarian Universalist Association and the Unitarian Universalist Ministers Association discourage the ordination of those who have not had academic and practical training provided by an accredited theological school, and who have not been welcomed into preliminary fellowship. How a congregation determines whom they will ordain is determined by congregational polity.
When the ordination date has been set, an ordination certificate may be requested by completing this form: ORDINATION CERTIFICATE REQUEST
We suggest you request the document at least two weeks prior to your ordination. It is highly recommended that all signatures be collected at the event. Once the certificate is complete, send a scanned copy via email to ministry [at] uua [dot] org. Alternatively, you may mail a photocopy to UUA, Julie Shaw, 24 Farnsworth St., Boston, MA 02210. The certificate will be placed in the minister's file.
An Ordination and Installation Manual (PDF) is available for suggestions on planning the service. While this document is somewhat dated, it remains one of the most comprehensive resources for these events.
