§1. Lay persons who possess the age and qualifications established by decree of the conference of bishops can be admitted on a stable basis through the prescribed liturgical rite to the ministries of lector and acolyte. [Cf. Letter of the Holy Father to the Prefect of the Congregation for the Doctrine of the Faith regarding access of women to the ministries of Lector and Acolyte (10 January 2021)] Nevertheless, the conferral of these ministries does not grant them the right to obtain support or remuneration from the Church.
§2. Lay persons can fulfill the function of lector in liturgical actions by temporary designation. All lay persons can also perform the functions of commentator or cantor, or other functions, according to the norm of law.
§3. When the need of the Church warrants it and ministers are lacking, lay persons, even if they are not lectors or acolytes, can also supply certain of their duties, namely, to exercise the ministry of the word, to preside over liturgical prayers, to confer baptism, and to distribute Holy Communion, according to the prescripts of the law.
