The Association known as Memores Domini unites the members of Communion and Liberation who follow a vocation of total dedication to God while living in the world.
The principal factors of the life of the Memores Domini are contemplation, understood as tending to keep one’s mind constantly trained on Christ, and mission, i.e., the passion for carrying the Christian announcement into the life of all men.

The Memor Domini "is a layperson who freely lives a life totally immersed  in the world with total personal responsibility” (Memores Domini – Interview with Msgr Luigi Giussani) and commits himself to the mission by living his professional occupation as the locus of the memory of Christ, in other words, by making it an offering.
Associates aim at pursuing a life of Christian perfection by practicing the Evangelical Counsels “which can be synthesized into the categories in which the Church traditionally summarizes the imitation of Christ. Obedience, in the sense that the spiritual effort and the ascetic life are made easier and more authentic by sequela. Poverty, as detachment from individual possession of money and things. Virginity, as giving up a family in favor of a total devotion to Christ also in a formal sense” (interview cited above).
The Memores Domini – sometimes called the “Adult Group” – practice a common  life in houses whose purpose is mutual edification for memory in view of the mission, sustained by a climate of silence, common prayer, and fraternal sharing.

The Memores Domini originated in Milan in 1964, within the sphere of the experience of Gioventù Studentesca.

After spreading through various dioceses, the Association was erected canonically by the Bishop of Piacenza, Msgr Enrico Manfredini, on 14 June 1981. Seven years later, on 8 December 1988, the Memores Domini were approved by the Holy See, which recognized their juridical status as a “Private Universal Ecclesial Association.”

The Memores Domini are present in 31 countries besides Italy.
