The word “simplicity” is a moral trait describing purity of motive. It is an openness and sincerity in sharing with others. It means “generosity, liberality”. The infant church in Jerusalem after Pentecost demonstrated such a spirit – Acts 2:44-45 “And all that believed were together, and had all things common; 45 And sold their possessions and goods, and parted them to all men, as every man had need.”
