Cavaradossi;10971092]Then by this logic, the Son is the Father. Your logic confuses a hypostatic property of the Father, causality, with being a natural property which is common to all.
Wait a minute Cavaradossi, you are mixing two things here from the filioque and confusing this process of procession with what is confirmed by the filioque as being consubstantial with God the Father who is principle without principle. It appears you are forcing the Spirit "who proceeds from the Father, that He comes from the Father through the Son. We never object to this professed faith and we don’t confuse this with the consubstantial nature of the Trinity which you appear to be doing with the filioque.
You mentioned “we don’t need the filioque”; The Church professed we do. Because the Arians were using the procession of the Holy Spirit coming distinctly from the Father and not from the Son. The Arians were proving the Nicene creed wrong, by holding that if the Holy Spirit only proceeds from the Father and never the Son, then the Son is created by the begetting of the Father, thereby suspending the professed Creed that the Son is a creature not God.
The Church rebutted this heresy with “Filioque”, not to denounce that the Holy Spirit proceeds from the Father through the Son which deals with the Father being God as the principle without principle.
Filoque confirms the Son as being God from the professed consubstantial communion which is in the Creed. The Orthodox holding of the Father as principle without principle is not professed in the Creed. Although we all hold to this same faith the Father as principle without principle. This was not enough to eliminate the Arian heresy who were trying to infect the Nicene Creed from the procession.
The reason we need the filioque is never to refute God theFather as principle without principle. But to prove that the Son is God, because of “the eternal order of the divine persons in their consubstantial communion and that the first origin of the Holy Spirit is from this principle without principle” CCC 248.
Filoque is professing the consubstantial communion between the Father and the Son, which defeated the Arians heresy in the West. Filioque never refutes the Father as the principle without principle.
Consubstantial communion proves that “as Father of the Only Son, He is with the Son, the single principle from which the Holy Spirit proceeds”, thus proving that the Son is God. And if the Holy Spirit proceeds from the Father from the consubstantial communion the Holy Spirit proceeds “and from the Son” (filioque). The filioque is introduced to defeat heresy and compliments the consubstantial communion between the Father and the Son which is what is professed from the Nicene creed.
The CCC strictly states however that “this complimentary of filioque to the consubstantial communion in the Father and the Son is never to become rigid and it is to never affect the identity of faith in the reality of the same mystery confessed”.
In summary the Orthodox position is correct because they along with us profess that God the Father is “the principle without principle”. But the Arians were not using the Creed at this time to refute the divinity of Christ, the Arians were rejecting the Nicene Creed.
Later the Arians were adopting the Nicene Creed but interpreting it into heresy.
The Roman Catholic position is correct which never leaves the professed faith from the creed of the Son being consubstantial with the Father. When we profess the consubstantial communion from the Creed it is from this communion that the Father is with the Son, the single principle from which the Holy Spirit proceeds, and if the HolySpirit proceeds from this consubstantial communion then the Son is God and therefore the HolySpirit proceeds from the Father and the Son. This “filioque” is needed to defeat all heresies who deny Jesus the only begotten Son of the Father as God, because the Son is consubstantial with the Father.
If one becomes too rigid in this filioque or makes more than what the CCC teaches, one mistakenly invents his own demi-god.
Peace be with you
