To live a Eucharist-centered life and be a missionary are the twin dimensions of the charism of the CFMSS. The core of its identity is centered on the Eucharist

- the very spring and pivot of individual and communitarian life: “a complete immolation of ourselves to Jesus along with Jesus in the Blessed Sacrament, in continuous reparation, and indefatigable apostolate.” Consequently, the CFMSS live by the Eucharist and draw from the Eucharist the strength for their life,offering themselves along with the Eucharistic victim on the Altar through a daily life of immolation, atonement, thanksgiving and surrender to God’s will.
