M.U.S.E.U.M. is the acronym of the motto of the Society:Magister Utinam Seguatur Evangelium Universus Mundus: 
May the whole world follow the Gospel. Evangelisation is the main goal of the Society. However, no one can give from what he/she does not possess.

Thus, the other goal of the Society is to keep oneself updated with the Church teachings in order to be a resource of knowledge. This is done by self-directed learning and community learning through the daily Assignment in the local centres.
