Eucharistic Minister, narses. Lay ministers, as opposed to ordained ministers.

It is my understanding that the Vatican has recently clarified (restated) these terms through the Congregation for Devine Worship in Redemptionis Sacramentum. What I think folks have been referring to as EEM (Extraodinary Eucharistic Ministers) lay ministers, should be referred to as Extraodinary Ministers of Holy Communion. Deacons, whether transitional or permanent, should be referred to as Ordinary Ministers of Holy Communion (Sinkspur), and, only a priest should be called an Ordinary Minister of the Eucharist.

So, when Card. Ratzinger states"The minister of Holy Communion must refuse to distribute it"It sounds as though he is specifically referring to lay or Extraodinary Ministers of Holy Communion and to transitional and permanent deacons as Ordinary Ministers of Holy Communion
