The Commission on Ministry is a diocesan body charged with assisting congregations help their members find the ministry to which God calls them, whether lay or ordained. The COM has published a document, Guidelines for the Discernment of Ministry in the Diocese of Hawai‘i, that describes ministries in the Episcopal Church and considerations for discernment. This document dates from 2005 and is in the process of being updated.

In addition, the COM hosts an occasional "Discernment Day" for interested people in the Diocese, at which ministries and processes for discernment are described.
