The Societas Doctrinae Christianae M.U.S.E.U.M. (Society of Christian Doctrine) was founded by Blessed George Preca in 1907 for Catholic lay men and women who want to dedicate themselves fully to God and to help the Church in the faith formation of children, youths and adults.

Fr Preca was declared Blessed in May 2001.

The Society in Malta has 53 Centres for men [nearly one in every parish] and in some larger parishes sub-branches of the same centre exist. The women's section has 43 Centres. In the nearby island of Gozo, there are 10 Centres for men and 7 for women.
The main priority of the Society is catechetical work in the parishes. Every evening all the Society's Centres are open for the catechetical formation of children and youths and occasionally adults as well. All Members are expected to participate in this activity after their normal day's work. After their catechetical classes, the Members participate in a daily one-hour session for their own on going formation in Church doctrine and related studies, pedagogical training and communal prayer. Such activities take place on all days of the week including Saturdays and Sundays. Every Wednesday a general meeting of all Members of the Society resident in Malta takes place in the Society's Mother House. Additional activities are organised especially for the children to include recreational and related activities. The Society also organises specialised courses for its basis on a national scale.
