>if you do/don't do X like my church it means you believe Y heresy
Dumb and petulant
Whether the spirit proceeds from the Son and the Father or just the Father is such a nuanced and complicated issue, both sides are entirely reasonable. The controversy wasn't even about the doctrine, it was about the west's authority to introduce the phrase into the creed.
The west definitely wasn't motivated by aristotelianism to add the filioque clause, that's just historically illiterate. Aristotle wasn't even translated into Latin until the Muslim Averroes in the 1100s, then brought into christian theology in the 1200s by Alexander of Hales.
Catholics don't offer wine at communion. Does that mean they deny that Christ shed his blood?
Most of us don't baptize three times. Does that mean we deny the trinity?
In the west the heresy to stop was Arianism, and the filioque clause helped btfo the Arians. The east got understandably upset at the precedent it set to unilaterally add to a creed.
