Acolyte used to be one the Minor Orders of the Church (Tonsure, Porter, Lector, Acolyte) that were conferred on men as they progressed through the seminary. There were three Major Orders that followed (Subdeacon, Deacon, and Priest).
Following Vatican II, all the orders except Deacon and Priest were suppressed. Pope Paul made Lector and Acolyte ministries in the Church but opened them up to laymen as well as candidates for the priesthood. (As these ministries are part of the seminary preparation for the priesthood, they are open to men only.)
Most dioceses in the U.S. (if not the world) confer the ministries of Lector and Acolyte only as part of the seminary formation program. My diocese (Lincoln, Nebraska) has had an extensive training program for laymen in these ministries for decades. A few other dioceses have similar programs.
Following is a post I made about this back in March of 2006:
I have been installed (that’s the term used on the certificates I received from the Diocese, both of which hang proudly in my office) as both a Lector and an Acolyte. I was installed in those ministries in 1983 and 1985 respectively and have served in those capacities in several different parishes since then.
Our late Bishop Flavin, in 1981, issued a decree that effective January 1, 1984, only installed Lectors and Acolytes could perform functions normally reserved to them at Masses in the Diocese of Lincoln. That is to say, to read at Mass, one had to be an installed Lector; to distribute Communion, one had to be an installed Acolyte. No readers, EMHCs, etc. The only exceptions to this decree were for Masses at or for Catholic schools and at convents. He also stipulated that all men who wished to be installed as a Lector or Acolyte had to be at least 21 years of age, and if they had children of school age, that those children be enrolled in Catholic schools (if available in their area). Bishop Flavin was a tremendous champion of Catholic schools.
Since the ministries of Lector and Acolyte are reserved to men only, this of course meant all women were “moved off the altar”, so to speak. Naturally, this caused a huge controversy, but Bishop Flavin remained firm and the Diocesan policy remained unchanged through his retirement in 1992.
Sometime after Bishop Bruskewitz came to Lincoln that in 1992, he relaxed the decree somewhat - allowing for non-installed readers to read the Scriptures at Mass. However, he continued the Diocesan training classes for the ministries of Lector and Acolyte. Today, it is the pastor’s option to allow readers (non-installed) to read the Scriptures at Mass, or to require Lectors (installed). I believe that the Bishop requires that at Masses where he is the celebrant, that only installed Lectors be used.
The way the two ministries function in most parishes is that the Lector acts as a reader would in your average catholic parish - announcing hymns, reading the Scriptures, General Intercessions, etc.
