It is stated in a document on the laity in the life of the Church.
Where, exactly?
I don’t remember exactly where I read that but it basically said. People who are acting in the Lay Ministries should be practicing Catholics in good standing with the church so as to not cause any scandal among the faithful. For instance a person who is divorced and has attempted another Marriage and cannot receive Holy Communion should not be an EMHC. A person who publicly opposes the Churches social or moral teaching, should not be proclaiming the readings at Mass.
I never considered singing in the choir to be a lay ministry. Nobody I know was ever commissioned to be a choir member.
I’m thinking this may be correct. There was some kind of document a while back that was negative about calling some of the ways the laity served in the Church “ministries”. It was held to possibly mislead folks into thinking that a layperson could supplant a priest.
While an interesting opinion, I don’t see it supported by any evidence.
That would depend on how someone looks at this specific liturgical function. Notice that I did not answer in a way specific to choir members. It is spoken of in many parishes as “Music Ministry” If this is proper or not I have no opinion, for I have never really thought about it or researched it.
