We show a special preference to give priority to the work of Evangelization including believers whose faith is weak, those who have gone away from faith, the new christians and the new believers. Through the activity of evangelization the gospel is proclaimed and explained . We proclaim the gospel both through deed and word and through a life of prayer and penance .
