But, they will say, how is it evident that the devil is accustomed to use testimonies of Holy Scripture? Read the Gospel. There it is written: "Then the devil takes Him," that is, the Lord Savior, "and sets Him on the pinnacle of the temple, and says to Him: If You are the Son of God, throw Yourself down; for it is written, He shall command His angels concerning You, to guard You in all Your ways, and on their hands they shall bear You up, lest You strike Your foot against a stone" (Mt 4:5-6; Ps 90:11-12). What will he not do to poor men, when he attacked the Lord Himself with testimony from the Scriptures? "If," he says, "You are the Son of God, throw Yourself down." Why? "For it is written," he says.
We must especially notice and remember the instruction contained in this passage. Knowing this example from the authority of the Gospel, when we see some people bringing apostolic or prophetic sayings against the catholic faith, we should not doubt at all that the devil speaks through their mouths. As the head then spoke to the Head, so now the members speak to the members: the members of the devil to the members of Christ, the treacherous to the faithful, the impious to the pious, heretics to the Orthodox.
What exactly do they say? "If you are a son of God, throw yourself down." That is, if you wish to be a son of God and inherit the kingdom of heaven, then "throw yourself down." Cast yourself down from the heights of the Church, which is also the temple of God. Leave her teaching and tradition. If someone asks any heretic who suggests this to him, "By what do you prove, and on what basis do you teach that I must leave the ancient universal faith of the Catholic Church?" he will immediately answer. "For it is written." At once he will present you with a thousand examples and a thousand proofs from the Law, the Psalms, the Apostles, and the Prophets. By interpreting them in a new and evil manner, he casts the wretched soul from the catholic ark into the abyss of heresy.
As for the promises that the devil then pointed to, heretics are astonishingly skilled at deceiving simple people with them. They dare to promise and teach that in their church, that is, in the gathering of their agreement, a great, special, indeed some particular grace of God is given. Thus everyone belonging to it, without any labor, zeal, or effort, even without asking, seeking, or knocking, enjoys such favor from God that, being borne on angels' hands and guarded by angels' protection, he can never "strike his foot against a stone" and can never be deceived.
What, then, someone will say, should Orthodox people, sons of the Mother Church, do when the devil and his disciples use divine utterances, sayings, and promises? Among them some are false apostles, others false prophets and false teachers, and all in general are heretics. How are they to distinguish truth from falsehood in view of the sayings of Holy Scripture? They must do as, according to the tradition of holy and learned men, we said at the beginning of this treatise. Namely, they must make sure that Holy Scripture is interpreted according to the traditions of the whole Church and according to the indications of catholic dogmatic teaching.
Within the catholic and apostolic Church itself, they must necessarily follow universality, antiquity, and agreement. Thus, if ever a part rises against the whole, novelty against antiquity, or the erroneous dissent of one person, or of a minority, against the agreement of all or at least the decisive majority of the Orthodox, they must prefer the incorruptness of universality to the error of a part. In the question of universality itself, they must prefer the piety of antiquity to the vileness of novelty. Finally, in the question of antiquity itself, they must prefer to the rashness of one person, or of a very limited number, above all the common definitions of some Ecumenical Council, if such exist on the given matter. If they do not exist, then they must prefer what is nearest to them, that is, the mutually concordant judgments of the majority of the great teachers. If, with God's help, we observe this faithfully, soundly, and diligently, then without great difficulty we shall discern every criminal error of newly appearing heretics.
It must be noted, however, that we are obliged with the greatest zeal to investigate and follow these concordant judgments of the ancient holy Fathers, not with regard to every minor question in Holy Scripture, but chiefly only concerning the rule of faith. On the other hand, not all heresies, and not always, must be refuted by this method, but only new and recent ones, appearing for the first time. As for ancient and long-established heresies, we have not the slightest need to approach them by this road. However ancient the vileness of such heresies or schisms may be, we must either strike them, if necessary, only by the authority of Holy Scripture, or flee from them without hesitation as already stricken by the teaching and condemned by the Ecumenical Councils of the Orthodox pastors of the Church. The end. And glory to our God!
