THE PROCESSION OF THE HOLY SPIRIT
Pontificial Council for Promoting Christian Unity
exerpt
The Catholic Church interprets the
Filioque with reference to the conciliar and ecumenical, normative and irrevocable value of the confession of faith in the eternal origin of the Holy Spirit, as defined in 381 by the Ecumenical Council of Constantinople in its Symbol. This Symbol only became known and received by Rome on the occasion of the Ecumenical Council of Chalcedon in 451. In the meantime, on the basis of the earlier Latin theological tradition, Fathers of the Church of the West like St Hilary, St Ambrose, St Augustine and St Leo the Great, had confessed that the Holy Spirit proceeds (
procedit) eternally from the Father and the Son.
Since the Latin Bible (the Vulgate and earlier Latin translations) had translated Jn 15:26 (para tou PatroV ekporeuetai) by “
qui a Patre procedit”, the Latins translated the ek tou PatroV ekporeuomenon of the Symbol of Nicaea-Constantinople by “
ex Patre procedentem” (Mansi VII, 112 B). In this way, a false equivalence was involuntarily created with regard to the eternal origin of the Spirit between the Oriental theology of the ekporeusiV and the Latin theology of the
processio.
The Greek ekporeusiV signifies only the relationship of origin to the Father alone as the principle without principle of the Trinity. The Latin
processio, on the contrary, is a more common term, signifying the communication of the consubstantial divinity from the Father to the Son and from the Father, through and with the Son, to the Holy Spirit. In confessing the Holy Spirit “
ex Patre procedentem”, the Latins, therefore, could only suppose an implicit
Filioque which would later be made explicit in their liturgical version of the Symbol.
In the West, the
Filioque was confessed from the fifth century through the
Quicumque (or “
Athanasianum”, DS 75) Symbol, and then by the Councils of Toledo in Visigothic Spain between 589 and 693 (DS 470, 485, 490, 527, 568), to affirm Trinitarian consubstantiality. If these Councils did not perhaps insert it in the Symbol of Nicaea-Constantinople, it is certainly to be found there from the end of the eighth century, as evidenced in the proceedings of the Council of Aquileia-Friuli in 796 (Mansi XIII, 836, D, ff.) and that of Aachen of 809 (Mansi XIV, 17). In the ninth century, however, faced with Charlemagne, Pope Leo III, in his anxiety to preserve unity with the Orient in the confession of faith, resisted this development of the Symbol which had spread spontaneously in the West, while safeguarding the truth contained in the
Filioque. Rome only admitted it in 1014 into the liturgical Latin version of the Creed.
