The Greek term paraklêtos (“paraclete”) appears four times in the Gospel of John (Jn 14, 16.26; 15, 26; 16, 7) and once in the First Epistle (1 Jn 2, 1). In the Gospel, its meaning is enigmatic. After a status quaestionis, a detailed analysis of paraklêtos in ancient literature reveals two different degrees of lexicalization: a) an embryonic stage conveying the idea of movement associated with a mandate, to be found in the Gospel (common usage in the Greek language)

b) the meaning of “intercesseur”, associated with a stereotyped triangular semantic structure, to be found in the Epistle (Jewish tradition). This term demands a moral qualification, supplied by the adjective “righteous” in 1 Jn and by the title “the Spirit of truth” in Jn; an evolution from the Epistle to the Gospel has taken place. The latter uses a term with a minimal semantic value to include it in the mission theme, by means of a recurrent prepositional strategy linked to the preverb para.
