Congar (1959, pp. 30–31) points out that provincialism – about theological terms which shape ideas in source languages but do not map to exact terms in target languages, including: prosōpon, hypostasis, and substantia – contributes to "estrangement on the level of thought and mutual understanding."

Boulnois (2003, pp. 106–107) notes that some ascribe an opinion about the Filioque to Cyril of Alexandria by "quotations grouped in anthologies" without analysis or context. The reason Cyril asserted a dependence was "the continuity between economy and theology" in his analysis of the relationship between the Son and the Holy Spirit. Cyril's reasons "correspond to different mechanisms" within the Trinity "which break up the simplistic opposition between the Latin schema of the triangle and the Greek model of the straight line." Boulnois thinks it is "impossible to classify Cyril unilaterally by applying [ ] a later conflict which, [ ] is largely alien to him." Boulnois, Marie-Odile (2003).

Meyendorff 1986, §2: "Blemmydes [... was] committed to [...] church unity and defended the idea that the image of the Spirit's procession 'through the Son', can serve as a bridge between the two theologies. [... He] collected patristic texts using the formula 'through the Son' and attacked those Greeks who out of anti-Latin zeal, were refusing to give it enough importance. In general, and already since Photius, the Greek position consisted in distinguishing the eternal procession of the Son from the Father, and the sending of the Spirit in time through the Son and by the Son. This distinction between the eternal processions and temporal manifestations was among the Byzantines the standard explanation for the numerous New Testament passages, where Christ is described as 'giving' and 'sending' the Spirit, and where the Spirit is spoken of as the 'Spirit of the Son'. In his letters [...] Blemmydes [...] avoided the distinction between eternity and time: the patristic formula 'through the Son' reflected both the eternal relationships of the divine Persons and the level of the 'economy' in time."

Meyendorff 1986, §3: "The Orthodox side ... was gradually transcending a purely defensive stand, by discovering that the real problem of the Filioque lies not in the formula itself, but in the definition of God as actus purus as finalized in the De ente et essentia of Thomas Aquinas, vis-à-vis the more personalistic trinitarian vision inherited by the Byzantines from the Cappadocian Fathers."
