For Luke the Evangelist, God’s encounter with Man is a salutary event. But what exactly does he mean when he speaks of “Salvation”, and how does this salutary encounter come about? Luke thinks differently from Paul here, but his position can only be deduced indirectly from his accounts (St. Luke’s Gospel and The Acts of the Apostles). The present study is the first to succeed in reconstructing in an overall framework the content of the ideas of “salvation” which Luke presupposes as an author and to demonstrate their consistency.
