My uncle suddenly passed away. My aunt (his spouse) is not Catholic, but we were able to have a Funeral Mass. His cremated remains are with my aunt in an urn that she wants placed in a mausoleum. She is considering interning him in a Catholic cemetery with a Committal performed by a Catholic priest of deacon. However, she wants to keep some of the ashes.
If we can’t convince her, can his cremated remains still be interned even if she is keeping some?
