What is the difference between a memorial mass and the full christian funeral?

Any Mass celebrated for a deceased person could be called a Memorial Mass or Memorial Service. This type of Memorial Mass or Service is celebrated when either no Funeral Mass has been celebrated or the Funeral Mass was celebrated in one place and the body is being transferred to another for burial. The difference is that a Memorial Mass takes place without either the body or the cremated remains present. The funeral usually has a Service along with a viewing and has the body or cremated remains present.
