Lectors are members of the Assembly who proclaim the Word in the first two scripture readings. They also assist in creating a hospitable and prayerful environment by praying the Prayers of the Faithful.

Speaking of readers at the Liturgy, Vatican II said, "They excercise a genuine liturgical function. They ought, therefore, to discharge their office with the sincere piety and decorum demanded by so exalted a ministry and right expected of them by God's people. Consequently, they must all be trained to perform their functions in a correct and orderly manner... Christ is present in His word since it is He Himself who speaks when the Holy Scriptures are read in the church."

A Eucharistic Minister distributes holy communion, as a minister of the host, or minister of the cup either at Mass, or carries the host to the sick, homebound, or hospitalized.

On January 29, 1973, Pope Paul VI issued an instruction Immense Caritatis (of Immense Love) on "Facilitating Sacramental Communion in particular circumstances." In his instruction, Paul VI lists the qualities which, ideally, should be present in the minister of communion.

"The person who has been appointed... must be duly instructed and should distinguish himself by Christian life, faith, and morals, striving to be worthy of this great office, cultivating devotion to the Holy Eucharistic and acting as an example to the other faithful by peity and reverence for this most holy sacrament of the altar. Let no one be chosen whose selection may cause scandal among the faithful."
