So are you RCC or Eastern Orthodox?
Filioque (Ecclesiastical Latin: [filiˈɔkwe]), Latin for "and (from) the Son", is a phrase included in some later forms of the Nicene Creed but not others, not appearing in the original version. It has been the subject of great controversy between Eastern and Western churches.
The council of Florence defined the filioque to mean "and (through) the Son" . The argument between current Orthodox & Catholic theologians has more to do with the use of the Greek words aitia (cause) and arche (source). The Catholic theologians at the council of Florence used the word aitia to mean a cause whether first, second, or immediate while the Orthodox theologians present used it (seemingly exclusively) as first cause. The linguistic and cultural as well as philosophical differences between the Catholic Latin-speaking Christians of the western kingdoms and the Orthodox Greek-speaking Christians of the Byzantine empire was known and understood by the theologians at the council but not by the general population of either group. The result was that the decisions of the Council of Florence were received in the West by the Catholic Church but never really gained great acceptance among the people and the decisions of the council were rejected by the people in the Byzantine empire thus bringing to an end the attempt to re-unite the Catholic and Orthodox communities.
The word arche was not used in the canons of the council of Florence yet some current Theologians include it in their explanations of why the council failed to achieve reunion.
EWTN gives the following translation of the text of the relevant section of the documents from the council of Florence:
Let the heavens be glad and let the earth rejoice. For, the wall that divided the western and the eastern church has been removed, peace and harmony have returned, since the corner-stone, Christ, who made both one, has joined both sides with a very strong bond of love and peace, uniting and holding them together in a covenant of everlasting unity. After a long haze of grief and a dark and unlovely gloom of long-enduring strife, the radiance of hoped-for union has illuminated all.
Let mother church also rejoice. For she now beholds her sons hitherto in disagreement returned to unity and peace, and she who hitherto wept at their separation now gives thanks to God with inexpressible joy at their truly marvellous harmony. Let all the faithful throughout the world, and those who go by the name of Christian, be glad with mother catholic church. For behold, western and eastern fathers after a very long period of disagreement and discord, submitting themselves to the perils of sea and land and having endured labours of all kinds, came together in this holy ecumenical council, joyful and eager in their desire for this most holy union and to restore intact the ancient love. In no way have they been frustrated in their intent. After a long and very toilsome investigation, at last by the clemency of the holy Spirit they have achieved this greatly desired and most holy union. Who, then, can adequately thank God for his gracious gifts?' Who would not stand amazed at the riches of such great divine mercy? Would not even an iron breast be softened by this immensity of heavenly condescension?
These truly are works of God, not devices of human frailty. Hence they are to be accepted with extraordinary veneration and to be furthered with praises to God. To you praise, to you glory, to you thanks, O Christ, source of mercies, who have bestowed so much good on your spouse the catholic church and have manifested your miracles of mercy in our generation, so that all should proclaim your wonders. Great indeed and divine is the gift that God has bestowed on us. We have seen with our eyes what many before greatly desired yet could not behold.
For when Latins and Greeks came together in this holy synod, they all strove that, among other things, the article about the procession of the holy Spirit should be discussed with the utmost care and assiduous investigation. Texts were produced from divine scriptures and many authorities of eastern and western holy doctors, some saying the holy Spirit proceeds from the Father and the Son, others saying the procession is from the Father through the Son. All were aiming at the same meaning in different words. The Greeks asserted that when they claim that the holy Spirit proceeds from the Father, they do not intend to exclude the Son; but because it seemed to them that the Latins assert that the holy Spirit proceeds from the Father and the Son as from two principles and two spirations, they refrained from saying that the holy Spirit proceeds from the Father and the Son. The Latins asserted that they say the holy Spirit proceeds from the Father and the Son not with the intention of excluding the Father from being the source and principle of all deity, that is of the Son and of the holy Spirit, nor to imply that the Son does not receive from the Father, because the holy Spirit proceeds from the Son, nor that they posit two principles or two spirations; but they assert that there is only one principle and a single spiration of the holy Spirit, as they have asserted hitherto. Since, then, one and the same meaning resulted from all this, they unanimously agreed and consented to the following holy and God-pleasing union, in the same sense and with one mind.
In the name of the holy Trinity, Father, Son and holy Spirit, we define, with the approval of this holy universal council of Florence, that the following truth of faith shall be believed and accepted by all Christians and thus shall all profess it: that the holy Spirit is eternally from the Father and the Son, and has his essence and his subsistent being from the Father together with the Son, and proceeds from both eternally as from one principle and a single spiration. We declare that when holy doctors and fathers say that the holy Spirit proceeds from the Father through the Son, this bears the sense that thereby also the Son should be signified, according to the Greeks indeed as cause, and according to the Latins as principle of the subsistence of the holy Spirit, just like the Father.
And since the Father gave to his only-begotten Son in begetting him everything the Father has, except to be the Father, so the Son has eternally from the Father, by whom he was eternally begotten, this also, namely that the holy Spirit proceeds from the Son.
We define also that the explanation of those words "and from the Son" was licitly and reasonably added to the creed for the sake of declaring the truth and from imminent need.
Also, the body of Christ is truly confected in both unleavened and leavened wheat bread, and priests should confect the body of Christ in either, that is, each priest according to the custom of his western or eastern church. Also, if truly penitent people die in the love of God before they have made satisfaction for acts and omissions by worthy fruits of repentance, their souls are cleansed after death by cleansing pains; and the suffrages of the living faithful avail them in giving relief from such pains, that is, sacrifices of masses, prayers, almsgiving and other acts of devotion which have been customarily performed by some of the faithful for others of the faithful in accordance with the church's ordinances.
Also, the souls of those who have incurred no stain of sin whatsoever after baptism, as well as souls who after incurring the stain of sin have been cleansed whether in their bodies or outside their bodies, as was stated above, are straightaway received into heaven and clearly behold the triune God as he is, yet one person more perfectly than another according to the difference of their merits. But the souls of those who depart this life in actual mortal sin, or in original sin alone, go down straightaway to hell to be punished, but with unequal pains. We also define that the holy apostolic see and the Roman pontiff holds the primacy over the whole world and the Roman pontiff is the successor of blessed Peter prince of the apostles, and that he is the true vicar of Christ, the head of the whole church and the father and teacher of all Christians, and to him was committed in blessed Peter the full power of tending, ruling and governing the whole church, as is contained also in the acts of ecumenical councils and in the sacred canons.
Also, renewing the order of the other patriarchs which has been handed down in the canons, the patriarch of Constantinople should be second after the most holy Roman pontiff, third should be the patriarch of Alexandria, fourth the patriarch of Antioch, and fifth the patriarch of Jerusalem, without prejudice to all their privileges and rights.
I asked as I was browsing Facebook and found something through a Catholic friend about this and was stumped at to what it was.
