7. Those who have no such revelation, and who judge according to their own wisdom, such as the Jews, Turks and heathen, must consider the Christian's declaration the greatest error and rankest heresy; they must say that we Christians are mad and foolish in imagining that there are three Gods, when, according to all reason—yea, even according to the Word of God—there can be but one God. It would not be reasonable, they will say, that there should be more than one householder over the same house, more than one lord or sovereign over the same government; much less reasonably should more than one God reign over heaven and earth. They imagine that thus with their wisdom they have completely overthrown our faith and exposed it to the derision and scorn of all the world. As if we were all blockheads and egregious fools and could not see their logic as well as they! But, thank God, we have understanding equal to theirs, and can argue as convincingly, or more so, than they with their Alkoran and Talmud, that there is but the one God.

8. Further, we know, from the testimony of Holy Writ, that we cannot expound the mystery of these divine things by the speculations of reason and a pretense of great wisdom. To explain this, as well as all the articles of our faith, we must have a knowledge higher than any to which the understanding of man can attain. That knowledge of God which the heathen can perceive by reason or deduce from rational premises is but a small part of the knowledge that we should possess. The heathen Aristotle in his best book concludes from a passage in the wisest pagan poet, Homer: There can be no good government in which there is more than one lord; it results as where more than one master or mistress attempts to direct the household servants. So must there be but one lord and regent in every government. This is all rightly true. God has implanted such light and understanding in human nature for the purpose of giving a conception and an illustration of his divine office, the only Lord and Maker of all creatures. But, even knowing this, we have not yet searched out or fathomed the exalted, eternal, divine Godhead essence. For even though I have learned that there is an only divine majesty, who governs all things, I do not thereby know the inner workings of this divine essence himself; this no one can tell me, except, as we have said, in so far as God himself reveals it in his Word.

9. Now we Christians have the Scriptures, which we know to be the Word of God. The Jews also have them, from whose fathers they have descended to us. From these, and from no other source, we have obtained all that is known of God and divine works, from the beginning of the world. Even among the Turks and the heathen, all their knowledge of God—excepting what is manifestly fable and fiction—came from the Scriptures. And our knowledge is confirmed and proven by great miracles, even to the present day. These Scriptures declare, concerning this article, that there is no God or divine being save this one alone. They not only manifest him to us from without, but they lead us into his inner essence, and show us that in him there are three persons; not three Gods or three different kinds of divinity, but the same undivided, divine essence.

10. Such a revelation is radiantly shed forth from the greatest of God's works, the declaration of his divine counsel and will. In that counsel and will it was decreed from all eternity, and, accordingly, was proclaimed in his promises, that his Son should become man and die to reconcile man to God. For in our dreadful fall into sin and death eternal, there was no way to save us excepting through an eternal person who had power over sin and death to destroy them, and to give us righteousness and everlasting life instead. This no angel or other creature could do; it must needs be done of God himself. Now, it could not be done by the person of the Father, who was to be reconciled, but it must be done by a second person, with whom this counsel was determined and through whom and for whose sake the reconciliation was to be brought about.

11. Here there are, therefore, two distinct persons, one of whom becomes reconciled, and the other is sent to reconcile and becomes man. The former is called the Father, being first in that he did not have his origin in any other; the latter is called the Son, being born of the Father from eternity. To this the Scriptures attest, for they make mention of God's Son; as, for instance, in Psalm 2, 7: "Thou art my son; this day have I begotten thee;" and again, Galatians 4, 4: "But when the fulness of the time came, God sent forth his Son," etc. From this it necessarily follows that the Son, who is spoken of as a person, must be distinct from the person of the Father.

12. Again, in the same manner, the Spirit of God is specifically and distinctively mentioned as a person sent or proceeding from God the Father and the Son: for instance, God says in Joel 2, 28: "I will pour out my Spirit upon all flesh," etc. Here a spirit is poured out who is God's, or a divine spirit, and who must be of the same essence, otherwise he could not say, "my Spirit;" and yet he must be a person other than he who sent him or who pours out. Again, because when he was sent he manifested himself, and appeared in his descent in a visible form, like that of a dove or tongues of fire, he must be distinct in person from both the Father and the Son.

13. But in this article of faith, in which we say that the Son of God became man and that he was of the same nature as we ourselves are, in order that he might redeem us from sin and death and give us eternal life without any merit or worthiness of our own, we give Jews and Turks no less occasion for laughter and mockery than when we speak of the three persons. For this is a more absurd assertion by far, in the estimation of human reason, which speculates in its Jewish and Turkish—yea, heathenish—teachings, on this wise: God is an only, almighty Lord of all, who has created all men and given them the law according to which they are to live; accordingly it follows that he will be merciful to the good and obedient, but will condemn and punish the disobedient. Therefore, he who does good works and guards himself against sin, God will reward. These are nothing but heathenish conclusions drawn from earthly, worldly experience and observation, as if God's government must be conducted on the same principles as that of a father among his children and domestics; for those are considered good rulers and masters who make a distinction with regard to their own interests.

14. Such heathen ideas of wisdom, holiness and service of God are taught and practiced by the Pope. And so we believed, myself and others, while we were under him, not knowing any better; otherwise we would have done and taught differently. And, in fact, he who has not this revelation and Word of God, can neither believe nor teach other than pagan doctrine. With such a faith, how much better were we than the heathen and Turks? Yea, how could we guard ourselves against any deception and lying nonsense that might be offered as good works and as service of God? Then we had to follow every impostor who came with his cowl and cord, as if Christ were represented in him; and we thought that in the observance of these things we would be saved. So the whole world was filled with naught but false service of God—which the Scriptures properly call idolatry—the product of human wisdom, which is so easily deceived by that which pretends to be a good work and to be obedience to God. For human wisdom knows no better; and how could it know better without the revelation? Even when the revelation was proclaimed, human wisdom would not heed it, but despised it and followed its own fancies. Hence it continued to be hidden and incomprehensible to such wisdom, as Saint Paul says: "For who hath known the mind of the Lord?"

15. But to us this counsel and mind of God in giving his Son to take upon himself our flesh, is revealed and declared. For from the Word of God we have the knowledge that no man of himself can be righteous before God; that our whole life and all our deeds are under wrath and condemnation, because we are wholly born in sin and by nature are disobedient to God; but if we would be delivered from sin and be saved, we must believe on this mediator, the Son of God, who has taken our sin and death upon himself, by his own blood and death rendering satisfaction, and has by his resurrection, delivered us. In this truth we will abide, regardless of the ridicule heaped upon us because of such faith, by heathen wisdom, which teaches that God rewards the pious. We understand that quite as well, if not better, than heathenism does. But in these mysteries we need a higher wisdom than our own minds have devised or can devise, a wisdom given to us by grace alone, through divine revelation.

16. For it is not our intention thus to pry into the counsel, thoughts and ways of God with our understanding and opinions, and to be his counselors, as they do who meddle in the affairs that are the prerogative of the Godhead, and who even dare, in the face of this passage of Saint Paul, to refuse to receive or learn of God, but would impart to him that for which he must recompense again. And thus they make gods after their own fancy, as many gods as they have thoughts; so that every shabby monastic cowl or self-appointed work, in their estimation, accomplishes as much and passes for as much as God the Father, Son and Holy Spirit, in their eternal divine counsel, determine and accomplish. And they continue to be nothing but wearers of cowls and instructors in works, which works even they can do who know nothing of God and are manifestly scoundrels. And even though they have long been occupied with these things, they still do not know how matters stand between themselves and God. And it will ever be true as Saint Paul says: "For who hath known the mind of the Lord, or who hath been his counselor?"

17. For your own theories—which are no more than what anyone can arrive at, conjecture or conceive in his own mind, without divine revelation—are not a knowledge of the mind of God. And what does it avail if you are not able to say more than that God is merciful to the good and will punish the wicked? Who will assure you that you are good and that you are pleasing to God with your papistic, Turkish monkery and holiness? Is it all that is necessary to assert: God will reward with heaven such as are faithful to the order? No, dear brother, mere presumption, or an expression of your opinion, will not suffice here. I could do that as well as you. Indeed, each may devise his own peculiar idea; one a black, and another a gray monk's cowl. But we should hear and know what God's counsel is, what is his will and mind. This none can tell you by his own understanding, and no book on earth can teach it except the Scriptures. These God himself has given, and they make known to us that he has sent his Son into the world to redeem us from sin and the wrath of God, and that whosoever believes in him should have everlasting life.
