@georgia @splitshockvirus You mean John 15:26?

But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me.

Originally

Ὅταν ἔλθῃ ὁ παράκλητος ὃν ἐγὼ πέμψω ὑμῖν παρὰ τοῦ πατρός,
τὸ πνεῦμα τῆς ἀληθείας ὃ παρὰ τοῦ πατρὸς ἐκπορεύεται,
ἐκεῖνος μαρτυρήσει περὶ ἐμοῦ.

From the Papyrus 66 which was discovered in 1952 near Jabal Abu Mana in Egypt as part of the Bodmer Papyri collection, dated around 200 AD.

From this Jesus is sending. Proceeding means something closer to creation when referring to the Holy Spirit. Ontologically God the Father is the source of all things, not the Son. The filioque started around 600AD as an attempt to explain spirits to germanic tribes, as far as I have learned.

It is good to appreciate the context. Western Rome fell apart decades after Christianity became the state religion. The bible was written in Greek which the East spoke, while Western Rome spoke Latin natively. So the East had hundreds of years with the text in their own language, with time and money to maintain that knowledge. While, over time a lot of linguistic confusion and desperate attempts of the clergy to remain in power without an empire muddied Western theology. An example of this is how much language had diverged. Kione Greek is pretty similar to modern Greek. But Latin is no longer spoken natively, and the jump from any romance language is rather high.
