Trinity Sunday
Text: Romans 11, 33-36.
33 O the depth of the riches both of the wisdom and the knowledge of God! How unsearchable are his judgments, and his ways past tracing out! 34 For who hath known the mind of the Lord? or who hath been his counsellor? 35 or who hath first given to him, and it shall be recompensed unto him again? 36 For of him and through him, and unto him, are all things. To him be the glory for ever. Amen.
THE ARTICLE OF FAITH ON THE TRINITY.
1. This epistle is read today because the festival of Holy Trinity, or of the three persons of the Godhead—which is the prime, great, incomprehensible and chief article of faith—is observed on this day. The object of its observance is that, by the Word of God, this truth of the Godhead may be preserved among Christians, enabling them to know God as he would be known. For although Paul does not treat of that article in this epistle, but touches on it only in a few words in the conclusion, nevertheless he would teach that in our attempts to comprehend God we must not speculate and judge according to human wisdom, but in the light of the Word of God alone. For these divine truths are too far above the reach of reason ever to be comprehended and explored by the understanding of man.
2. And although I have, on other occasions, taught and written on this article fully and frequently enough, still I must say a few words in general concerning it here. True, it is not choice German, nor has it a pleasing sound, when we designate God by the word "Dreifaltigkeit" (nor is the Latin, Trinitas, more elegant); but since we have no better term, we must employ these. For, as I have said, this article is so far above the power of the human mind to grasp, or the tongue to express, that God, as the Father of his children, will pardon us when we stammer and lisp as best we can, if only our faith be pure and right. By this term, however, we would say that we believe the divine majesty to be three distinct persons of one true essence.
3. This is the revelation and knowledge Christians have of God: they not only know him to be one true God, who is independent of and over all creatures, and that there can be no more than this one true God, but they know also what this one true God in his essential, inscrutable essence is.
4. The reason and wisdom of man may go so far as to reach the conclusion, although feebly, that there must be one eternal divine being, who has created and who preserves and governs all things. Man sees such a beautiful and wonderful creation in the heavens and on the earth, one so wonderfully, regularly and securely preserved and ordered, that he must say: It is impossible that this came into existence by mere chance, or that it originated and controls itself; there must have been a Creator and Lord from whom all these things proceed and by whom they are governed. Thus God may be known by his creatures, as St. Paul says: "For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity." Rom 1, 20. This is (a posteriori) the knowledge that we have when we contemplate God from without, in his works and government; as one, looking upon a castle or house 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.
