Joseph de Sainte-Marie, O.C.D.: "L' Eucharistie Salut du Monde.Etudes sur le Saint Sacrifice de la Messe, sa Célébration, sa Concélébration" Paris, Cèdre, 1982, 464 pThe author is a Carmelite, professor at the Faculty of Theology of his order in Rome. The book is of polemicalcharacter, composed as an answer to an article of Joseph Kleiner in "Esprit et Vie - L'Ami du Clergé" whoattacked an article of the author on concelebration.

To have real concelebration, the concelebrants must accomplish the action of Christ (singular!):mainly to pronounce the essential words.
