In 1671 Busée left Cologne and went to Vienna, where he lectured on the Holy scriptures in the university and taught Hebrew at the college of the Jesuits. In 1584 Busée went to Rome at the command of the General of the Society, Father Acquaviva, who had appointed him a member of a commission to draw up a system or plan of studies (Ratio Studiorum) for the entire Society. On his return to Vienna, Busée was made Rector of the College of Nobles and died while holding this position.
The following year, 1570, the work was completed, and was received at once with much favor. It consists of four volumes; for some unknown reason the last volume is lacking in the edition of the catechism, with notes by Busée, which was issued in 1571 by the house of Manutius of Venice, the descendants of Aldus Manutius. In 1577, a new edition, revised and augmented by another Jesuit, Jean Hase, was published at Cologne in one folio volume, under another title: Opus catechisticum ... D. Petri Canisii theologi S.J. præclaris divinæ Scripturæ testimoniis, sanctorumque Patrum sententiis sedulo illustratum operâ D. Petri Busæi Noviomagni, ejusd. Soc. theologi, nunc vero primum accessione novâ locupletatem atque restitutum.
