The sisters are deeply involved in catechetics at parish and diocese level.
They work at this in the parish of Satellite Town and in the Warri diocese, Delta State.
One sister has published five catechetical books for both catechists and students. These books are extremely well-written and illustrated, containing the most modern catechetical and theological information. They are now used in many dioceses throughout the country. Catechists in Satellite Town (Lagos) and Delta State have been systematically trained in their use.
The RCIA (Rite for the Christian Initiation of Adults) is the preferred method of initiation of new members into the faith in Nigeria and a lot of work goes into training the catechists who are involved in this programme.
