Mission travel has developed itself through the ages since it began long ago. Through the good work that they do and the areas they work in, missionaries have become explicitly conscious of social justice issues, and therefore today, they are more involved with resolving social justice issues.History of Mission TravelThe first missionary outreach of the Christian church dates back from the time of when St.Paul expanded his missionary work throughout the Roman Empire and beyond to Persia and India. Hundreds of years later, during the Middle Ages, the Christian monasteries and missionaries such as Saint Patrick propagated learning and religion well beyond the European boundaries of the old Roman Empire. Contemporary Catholic missionary work has undergone profound change since the Second Vatican Council of 1962-1965. While mission travel at the beginning was mostly focused on converting people to Christianity, modern mission travel focuses on helping the local population in tackling their immediate problems including inadequate basic needs and prevalent social injustices.Humanitarian goals became much more important for mission travelers, and they have become explicitly conscious of social justice issues. Many compassionate, faith-based organizations dedicate themselves to doing good for those in need. Countless organizations are helping to alleviate suffering and injustice for children, victims of natural disasters and other vulnerable groups worldwide.
