They have a great responsability in spreaching the Gospel to all people. In cooperation with the clergy, they should realize Jesus' teaching of love in the act of loving to each other, especially the sick, the poor, the suffer. They should promote human rights, justice, peace and common wealth in the society where they live. This is their mission based on the faith, Gospel and The Social Teaching of the Church.
