These errors {of the Reformed and others on the Incarnation}, and all that are contrary and opposed to the [godly and pure] doctrine presented above, we reject and condemn as contrary to the pure Word of God, the Scriptures of the holy prophets and apostles, and our Christian faith and confession. And we admonish all Christians, since in the Holy Scriptures Christ is called a mystery upon which all heretics dash their heads, not to indulge in a presumptuous manner in subtile inquiries, concerning such mysteries, with their reason, but with the venerated apostles simply to believe, to close the eyes of their reason, and bring into captivity their understanding to the obedience of Christ, 2 Cor. 10, 5, and to take comfort [seek most delightful and sure consolation], and hence to rejoice without ceasing in the fact that our flesh and blood is placed so high at the right hand of the majesty and almighty power of God. Thus we shall assuredly find constant consolation in every adversity, and remain well guarded from pernicious error.
