OL: What parish do you belong to?
YM: Well I live in Parish X but I attend mass in Parish Y where I am training to be an acolyte.
OL: Really? I became an acolyte many years ago....
Ummm. No you didn't. You may have been an altar server but never an acolyte.
First reference is Paul VI and Ministeria Quaedam:
7. In accordance with the ancient tradition of the Church, institution to the ministries of reader (lector) and acolyte is reserved to men.
Oops. Institution (permanent appointment - similar to ordination but NOT ordination) is reserved for men.
Second reference is to the so-called "escape" clause in Canon Law (link to relevant section):
Can. 230 s 1. Lay men who possess the age and qualifications established by decree of the conference of bishop scan be admitted on a stable basis through the prescribed liturgical rite to the ministries of lector and acolyte...
s 2. Lay persons can fulfil the function of lector in liturgical actions by temporary destination...
The first rule states that MEN can be instituted. The second states that ANYONE can do a similar function temporarily - in other words NOT instituted.
I guess it would be possible for OL to claim that canon law does not bind her but the challenge is that the claimed position is created by Canon Law - either you accept the creation and limitation OR you reject both. In either case, OL cannot be an instituted acolyte.
