One Spirit Or Another

Ερωτ ΛΗ’ Πῶς νοητέον τὸ, Πνεῦμα πονηρὸν παρὰ Κυρίον ἔπνιγε τὸν Σαούλ; Τοῦ θείου Πνευματος ἀποστάντος, χώραν ἔλαβε τὸ παμπόνηρον πνεῦμα. Διδασκόμεθα δὲ ἐντεῦθεν μετὰ τοῦ Δαβὶδ βοᾷν· Τὸ Πνεῦμά σου τὸ ἅγιον μὴ ἀντανέλῃς ἀπ' ἐμου. Οὕτω τῆς ἀποστολικῆς χάριοτς τὸν Ἰούδαν καταλιπούσης, εἰσελήλυθεν εἰς αὐτὸν ὁ διάβολος. Θεοδώρητος Ἐπίσκοπος Κύρρος, Εἰς Τὴν Πρωτην Τῶν Βασιλειων Source: Migne PG 80.564d

Question 38 How should it be understood that 'An evil spirit from the Lord troubled Saul' 1 When the divine Spirit has withdrawn, the wicked spirit takes its place. Which we are taught when David cries out: 'Do not take your Holy Spirit from me.' 2 Likewise the devil entered into Judas when the Apostolic grace left him. 3 Theodoret of Cyrrhus, Questions On The First Book Of Kings 1 1 Kings 16.14 2 Ps 50.11 3 Jn 13.27
