Masses

"Mass" is one of the names by which the sacrament of the Eucharist is called in the Roman Catholic Church, Latin liturgical rites, Western Rite Orthodox Churches, as well as in similar celebrations in Old Catholic Churches, in some Anglican parishes, and in many Lutheran Churches.

The term "Mass" is derived from the Late Latin word missa (dismissal), a word used in the concluding formula of Mass in Latin: "Ite, missa est" ("Go; it is the dismissal"). "In antiquity, missa simply meant 'dismissal'. In Christian usage, however, it gradually took on a deeper meaning. The word 'dismissal' has come to imply a 'mission'. These few words succinctly express the missionary nature of the Church".

mass (n.2)
"Eucharistic service," O.E. mæsse, from V.L. *messa "eucharistic service," lit. "dismissal," from L.L. missa "dismissal," fem. pp. of mittere "to let go, send" (see mission); probably so called from the concluding words of the service, Ite, missa est, "Go, (the prayer) has been sent," or "Go, it is the dismissal."

mass (n.1)
"lump, quantity, size," late 14c., from O.Fr. masse "lump, heap, pile; crowd, large amount; ingot, bar" (11c.), and directly from L. massa "kneaded dough, lump, that which adheres together like dough," probably from Gk. maza "barley cake, lump, mass, ball," related to massein "to knead," from PIE root *mag- "to knead" (cf. Lith. minkyti "to knead," see macerate). Sense extended in English 1580s to "a large quantity, amount, or number." Strict sense in physics is from 1704.
