My comments first: For years I have advocated for what Pope Francis accomplished today. That the ministries of lector and acolyte be opened to women in a formal way. I have advocated for years now, that there needs to be a codified way to admit men and women to these ministries and that the bishop is the one to install the laity into this ministry after proper screening and preparation.
As it concerns lectors at Mass, there is almost no mandate from the Church as it concerns who these volunteers will be (in terms of qualification, moral and academic) and no real program of ministry formation for these candidates.
In our diocese, parishes can pick whoever they wish to be both lectors and Communion Ministers. Once installed as acolytes, I presume Communion Ministers will be Ordinary not Extraordinary.
In our diocese at one time, Extraordinary Ministers of Holy Communion had to have their names submitted to the bishop who would by letter commission them for a period of three years. That has fallen by the wayside without any official promulgation by our last two bishops.
It seems that this Willy Nilly approach to these liturgical ministries of lector and Communion Minister is coming to an end and thank God for that.
