I agree with those who state that the laity may read from the Epistles, the Psalms, Proverbs, OT, and Gospel of John (& I think) from Revelation, but not sure about that last. Only a Priest or Deacon should read from the Gospels during Mass. This being said, laity MAY read the Gospel FROM the daily Mass in certain circumstances: i.e., I am also a Homebound Minister of the Eucharist, and take Holy Communion to the Homebound, those in Nursing Homes, or Hospitals. In the process, I read a portion of the Scriptures to them. Sometimes this is a short quote from the booklet “Communion of the Sick” , which is our approved guideline for Communion outside of Church. Sometimes I will read the Gospel from the day’s Mass to them, since they are unable to attend Mass due to illness or permanent infirmity. This is permitted. I have been a Lector at Masses, including Funeral Masses, which I frequently assist at. In these cases, I only read from the 1st or 2nd Readings or the Petitions of the Faithful, NEVER from the Gospel reading of the day, which is reserved to the Celebrant. At a Communion Service, I don’t remember, but I think when our Priest was gone, and we were without a Deacon, a member off the laity did read the Gospel reading for the day, but this was a Communion Service, definitely NOT a Mass.
