Objection #1: The scriptures do not mention it.
Reply: It doesn't matter if they do or not because the Church accepts both scripture and tradition. Furthermore, It seems implicit in some ofthe statements concerning the Holy Spirit coming from the Son as well.
I answer that, Yet, these are almost exclusivly western fathers and often fathers that taught other heresies as well. Further more, many more western and eastern saints have argued against it. Even many of the popes have argued against it.
Objection #2: The Fathers do not mention it.
Reply: Some of them do.
Objection #3: You can't change the creed.
Reply: The creed didn't exist prior to 325 A.D. and was changed at the next council.
I answer that: this was done with the consent of the Church. A few rogue bishops or a pope is not The Church. Furthermore, the Creed cannot change. It was added on to, but this was with the consent of the entire Church. The filoque on the other hand was done by a pope trying to increase his power and done on faulty theology.
"From Spain, the Filioque spread to the Germanic tribe of the Franks (in present-day France). It was embraced by Charlemagne who went so far as to accuse the East of having deliberately omitted it from the ancient Symbol. Pope Leo III (795-816) intervened, and forbade any interpolations or alterations in the Second Ecumenical Synod's Symbol of Faith. He ordered the Symbol Ã¢â‚¬â€ without Filioque Ã¢â‚¬â€ to be engraved in Latin and Greek on two silver plates and mounted on a wall of St. Peter's in Rome. The Franks ignored the pope and continued to use the Filioque. Many historians think Charlemagne used the Filioque in an attempt to justify his claim to be emperor in opposition to the Roman Empire (located in New Rome, also known as Constantinople). The dispute between East and West grew and became the focus of the Synod of Constantinople which met A.D. 879-880. This synod (recognised as the Eighth Ecumenical Synod by Orthodox Christians) reaffirmed the Symbol of A.D. 381 and declared any and all additions to the creed invalid. This synod's teaching was affirmed by the patriarchs of Old Rome (John VIII), New Rome [Constantinople] (Photius), Antioch, Jerusalem, and Alexandria and by Emperor Basil I.
Still, the Filioque continued to be used by the Franks and even spread to other Germanic tribes. Eventually, even Rome began to use the Filioque Ã¢â‚¬â€ at the coronation of Henry II in 1014 as emperor of the so-called Holy Roman Empire. Most historians agree the pope (Benedict VIII), due to his dependence on the Holy Roman Empire for military protection, acquiesed to its use. But from that point, Rome continued using the Filioque. In time, belief in the Filioque became dogma in Roman Catholicism"
Saint Cyril of Alexandria, The Twelve Anathemas, Error 9
We must not say that the one Lord Jesus Christ has been glorified by the Spirit, in such a way as to suggest that through the Spirit He made use of a power foreign to Himself, and from the Spirit received the ability to work against unclean spirits, and to perform divine signs among men; but must rather say that the Spirit, through whom He did indeed work His divine signs, is his own.
Saint Gregory of Palamas
On the one hand, the Holy Spirit is, together with the Father and the Son, without beginning, since He is eternal; yet, on the other, He is not without beginning, since He also Ã¢â‚¬â€ by way of procession, not by way of generation Ã¢â‚¬â€ has the Father as foundation, source, and cause. He also [like the Son] came forth from the Father before all ages, without change, impassibly, not by generation, but by procession; He is inseparable from the Father and the Son, since He proceeds from the Father, and reposes in the Son; He possesses union without losing His identity, and division without involving separation. He, also, is God from God; He is not different since He is God, yet He is different since He is the Comforter; as Spirit, He possesses hypostatic existence, proceeds from the Father, and is sent Ã¢â‚¬â€ that is, manifested Ã¢â‚¬â€ through the Son; He also is the cause of all created things, since it is in the Spirit that they are perfected. He is identical and equal with the Father and the Son, with the exception of unbegottenness and generation. He was sent Ã¢â‚¬â€ that is, made known Ã¢â‚¬â€ from the Son to His own disciples. By what other means Ã¢â‚¬â€ the Spirit which is inseparable from the Son Ã¢â‚¬â€ could He have been sent? By what other means could He Ã¢â‚¬â€ Who is everywhere Ã¢â‚¬â€ come to me? Wherefore, He is sent not only from the Son, but from the Father and through the Son, and is manifested through Himself.
Many blessings in Christ
