from without, would draw conclusions as to its lord or keeper.

      5. But from within (a priori) no human wisdom has been able to conceive what God is in himself, or in his internal essence. Neither can anyone know or give information of it except it be revealed to him by the Holy Spirit. For no one knoweth, as Paul says (1 Cor 2, 11), the things of man save the spirit of man which is in him; even so the things of God none knoweth save the Spirit of God. From without, I may see what you do, but what your intentions are and what you think, I cannot see. Again, neither can you know what I think except I enable you to understand it by word or sign. Much less can we know what God, in his own inner and secret essence is, until the Holy Spirit, who searcheth and knoweth all things, yea, the deep things of God—as Paul says above—reveals it to us: as he does in the declaration of this article, in which he teaches us the existence in the divine majesty of the one undivided essence, but in such manner that there is, first, the person which is called the Father; and of him exists the second person called the Son, born from eternity; and proceeding from both these is the third, namely, the Holy Spirit. These three persons are not distinct from each other, as individual brothers or sisters are, but they have being in one and the same eternal, undivided and indivisible essence.

      6. This, I say, is not discovered or attained to by human reason. It is revealed from heaven above. Therefore, only Christians can intelligently speak of what the Godhead essentially is, and of his outward manifestation to his creatures, and his will toward men concerning their salvation. For all this is imparted to them by the Holy Spirit, who reveals and proclaims it through the Word.

      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
