In distinction from both Waldhauser and Milič, Matthew obtained no special reputation as a preacher, but principally devoted his time to the composition of theological works. Some of these works attracted the attention of his superiors, and were condemned in 1388 by a Synod of the Archdiocese of Prague. Matthew was obliged to sign a document, which has been preserved to us by Palacký, in which he withdrew a considerable number of opinions contained in his works. In this recantation Matthew withdraws his former statements concerning images of Christ and the saints, which, indeed, he promises henceforth to "adore and venerate." He further affirms "that the saints in heaven, and their bodies and bones, and also other sanctified things, such as the garments of Christ, of the blessed Virgin, and of the saints, ought to be venerated here on earth." In the last paragraph of the recantation Matthew admits that people, specially laymen, should not be advised to receive communion daily. It is curious that Matthew's far-reaching theories concerning the return to primitive Christianity are not even alluded to in this recantation. As the chronology of the works of Janov--of which no single complete MS. has been preserved--is very uncertain, it is impossible to decide whether he had not then expressed these views, or whether it was thought advisable to leave them unnoticed. Matthew's sentence, no doubt in consequence of his recantation, was a very mild one; he was suspended from exercising his functions as a priest, except in his own parish church, during half a year. Janov died in the prime of his life in 1393, and retained his canonry up to that time.
