I know very well that in Romans 3 the word solum is not in the Greek or Latin text — the papists did not have to teach me that. It is fact that the letters s-o-l-a are not there. And these blockheads stare at them like cows at a new gate, while at the same time they do not recognize that it conveys the sense of the text – if the translation is to be clear and vigorous [ klar und gewaltiglich ], it belongs there. I wanted to speak German, not Latin or Greek, since it was German I had set about to speak in the translation. But it is the nature of our language that in speaking about two things, one which is affirmed, the other denied, we use the word allein [only] along with the word nicht [not] or kein [no]. For example, we say “the farmer brings allein grain and kein money”; or “No, I really have nicht money, but allein grain”; I have allein eaten and nicht yet drunk"; “Did you write it allein and nicht read it over?” There are countless cases like this in daily usage.
Inn diesen reden allen / obs gleich die Lateinische oder Griechische sprache nicht thut / so thuts doch die Deudsche / und ist ihr art / das sie das wort (Allein) hinzu setzt / auff das / das wort (nicht odder kein) deste völliger und deutlicher sey / Den wiewol ich auch sage / Der Bawer bringt korn und kein gelt / So laut doch das wort (kein gelt) nicht so völlig und deutlich / als wenn ich sage / Der Bawer bringt allein korn und kein gelt / und hilfft hie das wort (Allein) dem wort (kein) so viel / das es eine völlige Deudsche klare rede wird / denn man mus nicht die buchstaben inn der Lateinischen sprachen fragen / wie man sol Deudsch reden / wie diese Esel thun / Sondern man mus die mutter ihm hause / die kinder auff der gassen / den gemeinen man auff dem marckt drümb fragen / und den selbigen auff das maul sehen / wie sie reden / und darnach dolmetschen / so verstehen sie es denn / und mercken / das man Deudsch mit ihn redet. In all these phrases, this is a German usage, even though it is not the Latin or Greek usage. It is the nature of the German language to add allein in order that nicht or kein may be clearer and more complete. To be sure, I can also say, “The farmer brings grain and kein money,” but the words " kein money" do not sound as full and clear as if I were to say, “the farmer brings allein grain and kein money.” Here the word allein helps the word kein so much that it becomes a completely clear German expression. We do not have to ask the literal Latin how we are to speak German, as these donkeys do. Rather we must ask the mother in the home, the children on the street, the common man in the marketplace. We must be guided by their language, by the way they speak, and do our translating accordingly. Then they will understand it and recognize that we are speaking German to them.
