The term for a service without the presence of the deceased body is best described as?

A service conducted without the presence of the deceased body is best described as a memorial service. This term is specifically used to designate gatherings that honor and remember a person who has passed away, without the body being present. Memorial services often focus on celebrating the life and legacy of the deceased, allowing family and friends to share memories, express grief, and find comfort in one another’s support.

In contrast, a traditional service usually involves the presence of the deceased and may include specific rituals or customs associated with the person's cultural background. A humanistic service is typically non-religious and emphasizes personal values, but it does not inherently denote the absence of the body. An orthodox service is generally tied to specific religious practices and traditions, often with the deceased present. Therefore, the definition and characteristics of a memorial service align perfectly with the description provided in the question.
