Canon 591

Missionaries are to zealously take steps that: (1) vocations to

the sacred ministries are prudently promoted among the neophytes

so that the young Churches abound before long in native clerics;

(2) catechists are to be established so that, being valid cooperators of the sacred ministers, they can fittingly discharge

their function in the work of evangelization and in liturgical

activity; a just remuneration for the catechists is to be provided by particular law.
