Will a catholic priest perform a wedding in an episcopal church?
With the proper dispensation from the Ordinary (Local Bishop) of the diocese [usually obtained through the chancery office] and the couple has been instructed by going throught the Roman Catholic “Pre-Cana” courses, and the Catholic Party makes an oath that he/she will baptize, and educate, any children in the Roman Catholic faith, continuing to be a good example by the Catholic Faith he/she lives — and with the permission of the parish in which all records are to be filed, a Catholic Priest may assist at a ceremony (not a communion service) or accept the vows… whatever the wishes of the couple may be.
