In the Archdiocese of Portland, pastors and parochial vicars have the faculty to “allow Church funeral rites for an unbaptized child whose parents had intended to have the child baptized” and “for baptized members of non-Catholic ecclesial communities if requested by the family and provided this is not clearly contrary to the wishes of the deceased.”
Funeral rites may be celebrated in an adapted form for non-Christian members of a Catholic household (cf., OCF #398.36 and Part III, chapter 15).
Archdiocese of Portland:
• A priest/minister may not refuse funeral rites for a Catholic without the permission of the local Ordinary.
• The current Code of Canon Law does not prohibit an ecclesiastical funeral for someone who commits suicide. The OCF makes provision for a person who dies by suicide (cf., “Prayers for the Dead” OCF #398.44). For the purpose of arranging a funeral, a victim of suicide should be treated in the same manner as someone who dies of an untreated or incurable illness.
