The Father’s own voice, declaring, "This is My beloved Son" (Matthew 3:17), along with the angels who serve Him and the saints who have documented His life, adequately instruct the faithful that He is indeed the sole Son and Word of God. In contrast, the Arians, lacking pure understanding and unable to heed divine theologians, may as well take counsel from demons resembling themselves; these demons did not proclaim many sons but only recognized Him, stating, "You are the Holy One of God and the Son of God." The source of their heresy did not denote Him as merely one of God's saints, of whom there are many, but declared, "You are the Holy One of God," indicating His singularity. Therefore, the addition of the term "the Holy One" is significant here. He is holy by nature, while others achieve holiness through participation in Him. Likewise, even the purveyors of falsehood, often driven by necessity, inadvertently testify to the truth. Demons did not perform the work of Evangelists; instead, they were unable to confront the brilliance of truth and exclaimed: "Who are You, Holy God?"
