The term Mass of the Resurection has been used for the past forty years. It came into vogue when the revised missal began to be used in 1970, as a way of distinguishing the emphasis of the post-V2 rite on the hope of the resurrection. Funeral homes and newspaper obits have been particularly frequent users of the term, as it was seen as more ecumenical.
The Mass of the Resurrection, more properly known as a Mass of Christian Burial, uses white vestments, drapes a white pall over the casket to symbolize the white garment worn at baptism; indeed, baptism is mentioned frequently in the rite. The paschal candle is situated near the casket, and the texts speak repeatedly of the joy of the resurrection, and the hope that the deceased will join in it.
This is contrasted with a Requiem Mass, the pre-V2 version of the funeral Mass. The Mass is called Requiem because the first word of the introit is Requiem, i.e., rest. Black vestments are used in a requiem, to emphasize the release from sin and its consequences--for which we are praying for the dead to enjoy, as well as the mourning that is being done here on their behalf. Six tall candles, called bier lights, are placed around the casket during the Mass, rather than the paschal candle. The Dies Irae, a very somber piece of chant, is sung, among others.The theme of release from purgatory is much more evident in the rite.
I personally prefer the latter, and this is what my FSSP parish uses. I believe that the newer rites have, by both their abuse and even by their design, lent themselves to the instant canonizations that one hears commonly at modern funerals. However, the term Mass of the Resurrection has been in use for decades now, and does accurately reflect the orientation of the revised Mass texts. I would certainly not consider it a "trendy" term.
