The Congregation of the Missionary Sisters of Christ the King for the Polish Diaspora Abroad (MChr) (Latin: Congregatio Sororum Missionariarum Christi Regis pro Polonis Emigrantibus) - grew out of the spiritual and cultural needs of Polish emigrants.

[1][2] The vocation of each missionary is boundless love for the cause of God among the Polish diaspora abroad and the desire for self-sacrifice and joyful sacrifice of strength, comfort and life for the good of the Polish diaspora.

The sisters live in a community whose inner motto is Paul's exclamation: "May only Christ be proclaimed" (Phil 1:18).

Together with their immigrant brothers, they share the joys, sorrows and longings of everyday life.

In a foreign land, missionary sisters want to strengthen their faith and build a scrap of their beloved homeland by spreading the cult of the Eucharist, catechesis, and nurturing Polish culture, tradition and language.
