This paper argues that discipleship is a notion of growing importance to the Christian denominations and that the Marcan narrative of the call of the first disciples has been of particular importance in giving shape to this notion. The Lucan narrative of the call of the first disciple, involving the great catch of fish, is problematic in two ways, concerning its relationship with the Marcan understanding of call and also with the Johannine post-resurrection narrative. Against this background this paper reports on an empirical study, drawing on the reader perspective and on the SIFT approach to biblical hermeneutics, that illuminates the distinctive voices of sensing types and intuitive types reading Luke 5: 1-7
