In an excited
letter to Spalatin (on this occasion he was considered highly suitable for a discussion of the text), dated 14 December 1516, Luther wrote: «If reading a pure and solid theology, which is available in German and is of a quality closest to that of the Fathers, might please you, then get yourself the
sermons of Johann Tauler, the Dominican... I have seen no theological work in Latin or German that is more sound and more in harmony with the gospel
than this... Taste it and see how sweet the Lord is, [a quotation from the Psalms] after you have first tried and realised how bitter is whatever we are».
