These are the rules as summarized in the Archdiocese of Portland in Oregon:
Who may have a Catholic funeral liturgy?
Summary: Canons 1176 §1; 1183 §1, 2, and 3:
There is a fundamental right for Christians to have a Christian burial. Therefore,
according to the norms of law, deceased members of the faithful must be given
ecclesiastical funerals. In doing so, the Church seeks spiritual support for the
deceased as it honors their bodies and offers hope to the living.
With regard to funeral rites, catechumens, or those intending to receive baptism,
are counted among the members of the faithful and given the prerogative to have
an ecclesiastical funeral.
Similarly, children who have died prior to receiving baptism, but whose parents
intended baptism, may have an ecclesiastical funeral with the permission of the
local ordinary.
Baptized persons enrolled in non-Catholic Churches or ecclesial communities
may also be granted ecclesiastical funerals with the following conditions having
been met so as to respect the wishes of the deceased and to avoid any appearance
of proselytizing:
- the local ordinary, with the use of prudent judgment, gives such
permission;
- an ecclesiastical funeral would not be contrary to the intent of the
deceased person;
- the proper minister of the deceased is unavailable.
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.
