Mission is an issue of faith. This sentence hidden in the lengthy encyclical Redemptoris Missio captures a pivotal insight into the reality of mission. Mission is directly related to the depth and vitality of one's faith convictions. A sense of the urgency of mission only springs from living faith. The early Christians were fired with enthusiasm at Pentecost; they set out to the ends of the earth to give witness to their faith in Jesus as the crucified-risen Lord. Their faith and love of Jesus overcame great obstacles in preaching the Good News: they experienced a deepening in personal faith precisely as they shared their faith with others. Without doubt faith is always enriched when it freely shared through love and witness.
