Basil on the Spirit’s Procession from the Son

I was surprised while reading Basil’s On the Faith that he teaches that the Son sends the Holy Spirit in the same way the Father sends the Son, “The Holy Spirit does not speak from himself, nor does the Son do anything from himself, but the Father sends the Son, and the Son sends the Holy Spirit.” Basil is held in very high regard in Eastern Orthodoxy, which designates him the greatest of their three holy hierarchs. He’s a big deal in their tradition, which rejects the filioque clause on multiple grounds, including doctrinal. Yet Basil’s affirmation goes further than the contested filioque clause in the Nicene Creed, as he does not teach that the Spirit proceeds from the Father and the Son, just that the Son sends the Spirit.

The creed speaks of the Spirit coming from (ἐκπορευόμενον, a compound of ἐκ and πορεύομαι) and Basil speaks of the Son sending (πέμοντος). The cognitive similarities are clear, indicating that the doctrine in view is the same. But the dating here matters. On the Faith was likely written around 360 A.D., while the version of the Nicene Creed held by the church was not finished until the Council of Constantinople in 381. Basil’s terminology does not have the disputes surrounding the filioque clause in sight. However, Gregory of Nazianzus, in his important Oration 39 (Oration on the Holy Lights; §12) says “The Holy Spirit is truly spirit, coming forth from (προϊὸν; from προϊέναι) the Father indeed, but not after the manner of the Son, for it is not by generation but by ‘procession’ (ἐκπορευτῶς), since I must coin a word for the sake of clearness.” Gregory Nazianzen preached this in January 381, just before he led the Council of Constantinople. He crafted the term ἐκπορευτῶς for the economic relationship of the Holy Spirit to the Father, meaning that Basil would not have had those semantic nuances in mind 20 years earlier. Basil is not distinguishing the manners in which the Son and Spirit are sent (generation versus procession), respectively, but teaching that it is the Son who sends the Spirit as the Father sends the Son. Since ἐκπορευόμενον had not yet been coined, it is impossible to say whether Basil saw πέμοντος as closer to Nazianzen’s “procession” or προϊὸν. Be that as it may, Nazianzen is not ruling out the Son’s role in the Spirit’s procession, but asserting that the Spirit proceeds (ἐκπορευτῶς) from the Father, not that he is begotten (γεννητῶς) like the Son…
