SUSO, HEINRICH, blessed. – Spiritual writer and preacher, Dominican, born on 23 March 1295 (Bihlemeyer) or around 1300 (Gröber) at Constance, died on 25 January 1366 at Ulm, where he was buried. His tomb was destroyed under the Protestant regime. At the age of thirteen he entered the Dominicans in the convent on the Island near Constance, where, after five years, he began a heroic life of penance and prayer, of withdrawal and profound union with God, as a «servant» of Eternal Wisdom, even going so far as to carve the name of Jesus (IHS) on his chest. He completed his philosophical and theological studies at the convent school with those at the «Studium generale» of Cologne, where, Taulero (v.), around 1324 he listened to «the sweet doctrines of the holy master» (Eckart; V. ECCARDO). From 1327, lecturer at Constance.

S. is the most amiable of the German mystics and perhaps of all mystics universally. Without Eckart’s speculative boldness, without Tauler’s teleological clarity, S. surpasses both in delicacy and depth of feeling, in poetic inspiration and creative imagination. He knows how to express with great feeling the teaching of his masters, St. Bernard, St. Thomas, and Eckart. The theory of the purifications is formal and explicit. The ascent to God is necessary and must begin with a conversion (the first). S. does not speak of a general or special vocation. The beginner must remain in retreat and silence, mortify himself with moderation and prudence, renounce created things and persons, lose himself («wehtuender untergang») and become passive, giving himself to God. The second conversion takes place through meditation on the mysteries of Christ; Mary forms part of the way to God: S.’s chapters on Mary are tenderly filial; sufferings make one participate in the sorrows and merits of the Son of God. Finally, the soul attains mystical union in a transfiguration into God, its higher faculties being united with the supreme Being in vision, love, and supreme joyful enjoyment. S. summarizes his principles in the motto (Vita, l. II, chap. 4): «Entbildet werden von der creatur, gebildet werden mit Christus, überbildet werden in die Gottheit».
S.’s influence at the end of the Middle Ages was great throughout Europe, especially before the spread of the De imitatione Christi. Fischer and de Hornstein have treated the Susonian revival in the 19th and 20th centuries.
Of his writings, S. prepared a selection in 1362, called Exemplar, which contains: 1) the Vita, composed from information initially collected by Stagl and corrected and expanded by S.; it is the first autobiography in German literature, and its substantial authenticity has been defended; 2) the Libretto della verità (of 1326–27), which treats, in dialogue form, the highest mystical speculations against the «brothers» and «sisters of the free spirit» and in favor of Eckart;
3) the Libretto della Sapienza eterna, called by H. De-
nifle the most mature fruit of German mysticism, which, in
the form of a dialogue between Wisdom (Christ) and the servant,
reaches the pinnacle of literary art; it was extremely widespread,
as is shown by hundreds of manuscripts; 4) the Epistolario con-
taining 11 letters of spiritual direction of great psychological
and religious interest. Excluded from the Exemplar are: 1) the Horo-
logium Sapientiae, of 1333–34, dedicated to the master general
of the Friars Preachers; it is a Latin redaction or, according
to others, a precursor of the Büchlein der ewigen Weisheit;
extremely widespread, it was translated into more than six
languages; 2) some Sermoni; 3) the Grande epistolario with 27
or 28 letters; 4) the Minnebüchlein, published by W. Preger in
1896, though it is not accepted by everyone.
