In a letter dated 1532 to Duke Albrecht, he states his religious views clearly: "with the help of God he intends to remain in communion with the Church and allow all innovations to pass over like a disagreeable smoke". Crotus appears to have spent the last years of his life entirely at Halle, but nothing positive is known on the subject. Most probably Georg Witzel urged him at different times to write again in defence of the Catholic Church, and he seems, indeed, to have made an effort to do this. But afterwards we hear that the position, "unworthy of a man", in which he was placed, did not permit him to take up his pen on behalf of religion. It is not entirely certain whether his canonry or his character of official in the service of Cardinal Albrecht laid these limitations on him. Yet he apparently had an important influence on the writings of others as, e.g. on those of Witzel. He died probably at Halle, c. 1539

Crotus himself as a humanist of strong intellectual tastes, preferred above all the quiet of his study. It may be that the revolutionary tumult in religious and social life took from him both the desire and the strength to use the pen which had formerly so unmercifully scourged the weaknesses of his opponents. He seems, however, to have influenced the religious demeanour of his master, Cardinal Albrecht, in the cardinal's later years.
