Scholz attended secondary school at the Catholic gymnasium in Breslau and then studied at the University of Breslau. In 1817 he was granted the degree of Doctor of Theology by the University of Freiburg, where he had studied under Johann Leonhard Hug (1765-1846). Scholz then went to Paris, where he studied Persian and Arabic under Silvestre de Sacy, and collated numerous codices (Greek, Latin, Arabic and Syriac) of the New Testament.^[1] From Paris he went to London, then travelled through France and Switzerland en route to Italy, the principal libraries of which he visited in order to conduct biblical research. In the autumn of 1821, upon his return from a journey through Egypt, Palestine and Syria, and having been ordained at Breslau (in October 1821), Scholz became professor of exegesis at the University of Bonn, a chair to which he had been called in 1820, and which he filled until his death, despite the fact that he was not an interesting lecturer.^[2]

In 1837, Scholz was appointed canon of the Cologne Cathedral.

In addition to his major work, his Novum Testamentum Graece (a text edition of the Greek New Testament), Scholz was also known for his efforts in Bible translation, in which he continued the work begun by Dominikus von Brentano and Anton Dereser.

Scholz's work in textual criticism was particularly appreciated by the British. He was able to add to the list of Greek manuscripts of the New Testament 616 new minuscule manuscripts. His additions to the list of uncials comprise only Codex Sangallensis (Δ) and three fragments of the Gospels 0115 (formerly W^a), 054 (his Y),^[3] and the Vatican portion of N022 (his Γ). These manuscripts were partially examined and collated by him.^[4] Results of his work were published between 1830 and 1836.

Scholz's accession of new witnesses to the lists of New Testament manuscripts was extensive. He was responsible for adding codices 260-469 of the Gospels,^[5] 110-192 of the Acts, 125-246 of the Pauline epistles,^[6] 51-89 of the Apocalypse, 51-181 of the Evangelistaria, and 21-48 of the Apostoloi.^[7]

Scholz collated the entire text of five manuscripts: 262, 299, 300, 301 and 346. Other manuscripts he collated in large part: (260, 270, 271, 277, 284, 285, 298, 324, 353, 382 and 428).

Scholz divided all New Testament manuscripts into five families: two African (Alexandrian and Western), one Asiatic, one Byzantine and one Cyprian. He was the first to emphasize the importance of ascertaining the geographical provenance of a witness. That point was elaborated by B. H. Streeter in 1924 ("theory of local texts"). Scholz, after some tentative attempts at classifying manuscripts, rejected this theory and adopted Johann Albrecht Bengel's division into two families, which he called the Alexandrian and the Constantinopolitan. He initially favoured the Constantinopolitan (Byzantine) family of manuscripts, but in 1845 he retracted this preference for the Constantinopolitan .^[8]
