Floyd O. Parker, «Is the Subject of 'tetelestai' in John 19,30 'It' or 'All Things' ?», Vol. 96 (2015) 222-244
This article attempts to demonstrate that the unexpressed subject of tete/lestai in John 19,30 is 'all things' (pa/nta) rather than 'it', and that this subject should be supplied from the phrase pa/nta tete/lestai found earlier in the passage (John 19,28). The essay also argues that the two occurrences of 'all things' (John 18,4 and 19,28.30) encapsulate the passion narrative, and that this phrase is related to other Johannine themes in content and time frame (i.e. the 'hour', the 'cup', and the Passover).
