The Episcopal Church Canons require that every diocese have a Commission on Ministry (COM). In DioCal the main work of COM, in accordance with the canons, is concerned with the discernment of and call to ministry for all baptized persons. A primary focus is guiding and examining aspirants, postulants, and candidates in their discernment process for Holy Orders as well as making its recommendations to the bishop and Standing Committee.
You can learn more about the Commission on Ministry or COM on their recently updated webpage.
