Catechists must be well-formed:
Teachers and educators on the other hand, who carry on a distinguished form of the apostolate of the laity by their vocation and office, should be equipped with that learning and pedagogical skill that are needed for imparting such education effectively.
Lay groups should be attuned to passing the baton:
Likewise, lay groups and associations dedicated to the apostolate or other supernatural goals, should carefully and assiduously promote formation for the apostolate in keeping with their purpose and condition.
I was especially struck by these next words:
Frequently these groups are the ordinary vehicle for harmonious formation for the apostolate inasmuch as they provide doctrinal, spiritual, and practical formation. Their members meet in small groups with their associates or friends, examine the methods and results of their apostolic activity, and compare their daily way of life with the Gospel. Formation of this type must be so organized that it takes into account the whole lay apostolate, which must be carried on not only among the organized groups themselves but also in all circumstances throughout one’s whole life, especially one’s professional and social life.
Parents, schools, groups, all are responsible not just for promoting agendas, but for seeing their part of the apostolate in light of the Church’s overall mission as well as to assist individual young people to sort out their own call and path to God.
It only took the USCCB thirty-some years to emphasize adult faith formation, but the root of it was here:
Indeed, everyone should diligently prepare himself for the apostolate, this preparation being the more urgent in adulthood. For the advance of age brings with it a more open mind, enabling each person to detect more readily the talents with which God has enriched his (or her) soul and to exercise more effectively those charisms which the Holy Spirit has bestowed on him (or her) for the good of (others).
