As I understand it - these women are celebrating a Service of Holy Communion outside of Mass - i.e. there is no priest available
Quoted from the link given by mea kulpa
<<They still are not saying the Mass, but they carry out many functions that a priest normally does. From the altar they conduct the Sunday service, which consists in reading the Gospel and Epistle, commenting on them, directing the songs and prayers and distributing Communion to those present.
This practice has been encouraged by the priests themselves, as is the case of Fr. Manuel José Marques, who is in charge of seven parishes in the region of the Alentejo, Portugal. He directs a group of 16 laypeople – eight women and eight men – who give this type of assistance when he cannot be at one of his parishes.>>
<<
Fr. Marques says that there is nothing new in this practice since it was long planned by the Church and has been put into practice since the 1980s. He argues that these experiments have been made also in Germany, France, Switzerland and the United States. >>
And yes - I've quickly skimmed the articles that were linked from the Portuguese press - and with my exceedingly rusty and poor Portuguese understood exactly the same - these people are Extraordinary ministers of Holy Communion - they are not pretending to be priests , they are celebrating a service which is permitted when it is not possible to have the presence of a priest.
