If the Latin dogma is true that the Holy Spirit proceeds also from the Son, then ours is false that states that the Holy Spirit proceeds from the Father—and this is precisely the reason for which we separated from them. And if ours is true, then without a doubt, theirs is false. What kind of middle ground can there be between two such judgments? There can be none, unless it were some kind of judgment suitable to both the one and the other, like a boot that fits both feet. And will this unite us?
But, someone will say, how shall we regard those moderate Greco-Latins who, maintaining a middle ground, openly favor some of the Latin rites and dogmas—favor, but do not wish to accept others—and entirely disapprove of others? One must flee from them as one flees from a snake, as from the Latins themselves, or, it may be, from those who are even worse than they—as from buyers and sellers of Christ. For they, as the Apostle says, “suppose that gain is godliness” (1 Tim. 6:5), of whom he adds, “flee these” (1 Tim. 6:11), for they go over to them not in order to learn, but for gain. “What communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?” (2 Cor. 6: 14–15).
Behold how we, together with Damascene and all the Fathers, do not say that the Spirit proceeds from the Son; while they, together with the Latins, say that the Spirit proceeds from the Son.
And we, together with the divine Dionysios, say that the Father is the sole Source of the supernatural Divinity; while they, together with the Latins, say that the Son also is the Source of the Holy Spirit, and by this clearly excluding the Spirit from the Divinity.
And we, together with Gregory the Theologian, distinguish the Father from the Son in His capacity of being Cause; while they, together with the Latins, unite them into one in the capacity of being Cause.
And we, together with St. Maximos and the Romans of that time, as well as the Western Fathers, “do not make the Son the Cause of the Spirit”; while they, in their Conciliar Decree, proclaim the Son “in Greek, ‘Cause,’ and in Latin, ‘Principle'” of the Spirit.
And we, together with the Philosopher and Martyr Justin affirm, “As the Son is from the Father, so is the Spirit from the Father”; while they, together with the Latins, say that the Son proceeds from the Father immediately, and the Spirit from the Father mediately.
And we, together with Damascene and all the Fathers, confess that it is not known to us in what consists the difference between generation and procession; while they, together with Thomas and the Latins, say that the difference consists in this: that generation is immediate, and procession mediate.
And we affirm, in agreement with the Fathers, that the will and energy of the uncreated and divine nature are uncreated; while they, together with the Latins and Thomas, say that will is identical with nature, but that the divine energy is created, whether it be called divinity, or the divine and immaterial light, or the Holy Spirit, or something else of this nature—and in some fashion, these poor creatures worship the created “divinity” and the created “divine light” and the created “Holy Spirit.”
And we say that neither do the Saints receive the kingdom and the unutterable blessings already prepared for them, nor are sinners already sent to hell, but both await their fate which will be received in the future age after the resurrection and judgement; while they, together with the Latins, desire immediately after death to receive according to their merits. And for those in an intermediate condition, who have died in repentance, they give a purgatorial fire (which is not identical with that of hell) so that, as they say, having purified their souls by it after death, they also together with the righteous will enjoy the kingdom; this is contained in their Conciliar Decree.
And we, obeying the Apostles who have prohibited it, shun Jewish unleavened bread; while they, in the same Act of Union, proclaim that what is used in the services of the Latins is the Body of Christ.
And we say that the addition to the Creed arose un-canonically and anti-canonically and contrary to the Fathers; while they affirm that it is canonical and blessed—to such an extent are they unaware how to conform to the Truth and to themselves!
And for us, the Pope is as one of the Patriarchs, and that alone—if he be Orthodox; while they, with great gravity, proclaim him “Vicar of Christ, Father and Teacher of all Christians.” May they be more fortunate than their Father, who are also like him. For he does not greatly prosper, having an anti-pope who is the cause of sufficient unpleasantness; and they are not happy to imitate him.
