If the Spirit is “from” the Father and the Son, then he proceeds from both. Not in the sense of ekporeusis,but of “going forth”.
You are oversimplifying and conflating here.
The original phrase of our Symbol of Faith:
“We believe … in the Holy Spirit … who proceeds from the Father” is directly from John 15:26:
When the Paraclete comes, whom I shall send to you from the Father, the Spirit of truth who issues from the Father, he will be my witness. ~ John 15:26
You are conflating
‘temporal origin’ ( i.e. ‘I shall send to you from the Father’) with
‘eternal origin’ (i.e. ‘From the Father’).
The difference between the “eternal origin” and the “sending in time (temporal) origin” is important. Most attempts to support the
Filioque confuse the two or fail to recognize the difference. They are not the same.
St. Epiphanius:
“No one knows the Spirit, besides the Father, except the Son, from Whom He proceeds (proienai) and of Whom He receives.” (OP… cit., xi, in P.G., XLIII, 35):
Only in ‘temporal origin’. Break it apart. When you fail to make this distinction you are at least conflating the two person of the Father and the Son into one or at worst you are giving attribute to spirate to the Godhead which is then shared by the Father and the Son. Either way, it doesn’t appear to be the consensual teaching of the early Church.
Ask yourself…
Does the ability to “spirate” the Holy Spirit
come from the Godhead or from a specific Person?
If a specific Person, which one?
The Catholic Church doesn’t teach a dual procession either.
The Father and Son are one in being, so it is not a matter of dual procession, unless you think of the Father and Son as separate beings. The filioque doctrine is directly related to the doctrine of consubstantiality. There’s no real distinction between the eternal origin of the Spirit and it’s temporal manifestation,because the Spirit originates on earth is as in heaven – through the Son.
With this kind of logic wouldn’t we have to say that the Holy Spirit then spirates Himself as well?
You do see what you are doing don’t you? You are giving the attribute of spiration to the nature of God and saying that the Persons ‘share’ that attribute.
Pagan Greek ontology taught that God is first and foremost, His
substance or
nature. Heretics such as the Arians and Nestorians, working from this pagan Greek thought, taught that the substance or nature preceded God’s existence as Trinity, i.e. as Three Persons. This is the same interpretation that has come to prevail in Western Christian thought as can be seen by the typical arrangement of books on dogmatic and systematic theologies. (First is the existence of God, then the nature of God, then the attributes or qualities of God; all before the existence of the Trinity is broached.)
This interpretation is important inasmuch as it assumes
a priori that the ontological “principle” of God lies not in a Person, but in the
substance, the “being” of God. In the West, this has led to the belief that the unity of God consists of the one divine
substance.
This is a distortion of Patristic theology. Among the Fathers the unity of God, the “cause” of the being and life of God consists not in the one
substance of God, but in the
Person of the Father (His hypostasis). The one God is not the one substance, but the Father who begets the Son and “spirates” the Holy Spirit. Thus, God is not bound by some ontological “necessity” to exist. God exists because the Father exists, He who out of love freely and eternally begets the Son and freely and eternally “spirates” the Holy Spirit. Substance or nature does not exist in a vacuum, without a mode of existence (i.e. a
hypostasis or person, an individuation). The one divine substance/nature is the being of God
only because it has three modes of existence — Three Persons — which it owes not to the substance, but to the source (αρχή) of the Three: the Father. Apart from the Holy Trinity there is no God, no divine substance because the ontological “principle” of God is the Father. By regarding some Divine
substance as the source of the Holy Trinity, the existence of the Three Divine Persons is made a kind of logical
necessity, thus undermining the autonomy of the Holy Trinity. In the
Filioque, this emphasis on likeness of Divine
substance between the Father and the Son results in the subordination of the Holy Spirit.
