Debating an Eastern Orthodox, this segment was over the Papacy.


He is a man! Not God! Do you think he can modify the true faith established at the seven Ecuмenical Councils as he wants and still be considered Christian? He is not infaillible, not even the bishops of the Orthodox Church are.

When I said Church Fathers I was refering to the Saints after the Great Schism.

Here are more about details Filioque:
Rome resisted the inclusion of the filioque for centuries. Leo III, the Pope of Rome at the time the filioque began its history in Western theology, strongly advised against its inclusion, even though he agreed with the soundness and validity of the doctrine contained in filioque. Later, however, Rome contradicted its previous more Orthodox stance by the promulgation of the filioque, thus anathematizing its own spiritual forebears.

From:
http://en.wikipedia.org/wiki/Pope_Leo_III
Leo forbade the addition of filioque to the Nicene Creed, which was added by Franks in Aachen in 809. He also ordered that the Nicene creed be engraved on silver tablets so that his conclusion might not be overturned in the future. He wrote «HAEC LEO POSUI AMORE ET CAUTELA ORTHODOXAE FIDEI» (I, Leo, put here for love and protection of orthodox faith).[1]


Objections on doctrinal grounds
It is contrary to Scripture, particularly in John 15:26: "But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me." Thus, Christ never describes the Holy Spirit as proceeding from himself, but only mentions the Spirit's procession in terms of the Father.
The justifications for including the filioque in the Creed—bolstering the divinity of the Son and emphasizing the unity of the Trinity—are redundant, given the original wording of the Creed. That is, the Son already is described as "light of light, very God of very God," and so forth. The Spirit also "with the Father and Son together is worshiped and glorified." Additionally, the Creed itself begins with a statement of belief in "one God."
The filioque distorts Orthodox Triadology by making the Spirit a subordinate member of the Trinity. Traditional Triadology consists in the notion that for any given trait, it must be either common to all Persons of the Trinity or unique to one of them. Thus, Fatherhood is unique to the Father, while begottenness is unique to the Son, and procession unique to the Spirit. Godhood, however, is common to all, as is eternality, uncreatedness, and so forth. Positing that something can be shared by two Persons (i.e., being the source of the Spirit's procession) but not the other is to elevate those two Persons at the expense of the other. Thus, the balance of unity and diversity is destroyed.
Given the previous objection, the repercussions to the acceptance of the filioque into church life are potentially massive. Because how we relate to God is significantly affected by what we believe about him, false beliefs lead to damaging spirituality. One objection often raised about Filioquist theology is that it undermines the role of the Holy Spirit in the Church. Thus, with his role being denigrated, his traditional ministries are effaced or replaced. The Church's unity becomes dependent on an office, spirituality becomes adherence to the letter of the law rather than its spirit, sacraments come to be understood in terms of validity, and a spirit of legalism prevails.
