The zeal to share Eucharistic love urges us to go for mission work in any part of the world. Taking into account the needs of the church in India and abroad, we engage in mission work. We manifest our Eucharistic life in the context of the Church's teaching, oriental spirituality, and elements of Indian culture compatible with Catholic doctrine. In our missionary works our preferential option is to work in the developing countries among the poor, sick, illiterate, oppressed and the needy. Sharing the fruits of our Charism, we bring them to Eucharistic Jesus, the answer to all our problems. The congregation has houses in almost all the states of India as well as in continents, Europe Africa, North America and South America.  The sisters are open to the needs of the Church in India, disregarding the place, race, caste and creed to offer themselves for Evangelization. They are engaged in the field of education, healing ministry and social services of various kinds. Marvellous was the development and faster was the stride ever since 1965 as far as the Congregation is concerned. “We have 11 provinces and 1 region outside Kerala as mission provinces, of which Sion Province, East Africa is situated in the African countries of Kenya and Tanzania and Uganda. About 23% of our total sisters are engaged in mission works. The dedication and commitment of the sisters in Missions show in their apostolate and reflect in the vocations we get from the mission areas. Our services in mission areas are mostly rendered in Mentally Challenged Schools, Old Age Homes, Orphanages, AIDS Care Centres, Juvenile Homes, Deaf and Dumb Schools etc. We have dedicated sisters who have opted for global mission, and recruited candidates too who are interested are given formation with this in mind.  In the European countries too, we are engaged in Perpetual Adoration Centres, Pastoral work, Faith Formation etc.
