Prior to this [motu proprio](http://www.vatican.va/content/francesco/en/motu_proprio/documents/papa-francesco-motu-proprio-20210110_spiritus-domini.html) the only purpose of the order of acolyte or lector in the Catholic Church that I knew of was to prepare permanent deacons for ordination. So, if the purpose is expanded to all lay people, what function will acolytes perform in the future? Will we be expecting itinerant acolytes going from parish to parish helping at masses? Will we be wowed by one superior lector?

Our parish started Latin Masses a few months ago and I'm finally getting in the hang of it, but one thing I noticed is that the priest reads everything (except for a few things that the servers recite) but with Pope Francis' new moto proprio and a friend of mine who has recently been ordained a deacon choosing the lector ministry. What I don't know, is if this is a traditional role in the Church, what would a lector do prior to Vatican II?
