Scholarly Methodology and Controversy

Mastrius was known for a rigorous and precise intellectual style, yet his approach to academic debate was often combative. He frequently clashed with contemporaries, including Matthew Ferchi and the Irish Franciscan John Punch. He criticized Punch for allegedly failing to remain faithful to the methodology and conclusions of Scotus. When presenting his work to Alexander VII, he defended his sharp rhetorical style by drawing historical parallels to theological debates over the interpretation of scripture.

Published Contributions

His prolific output was largely published in Venice. Notable works include his five-volume Philosophy, four-volume commentaries on the Sentences, and the 1671 publication of Theologia ad mentem Scoti. He also produced a moral theology text oriented toward the thought of his order and edited the influential Philosophia ad mentem Scoti. These volumes demonstrated his critical capacity and deep familiarity with a wide array of ancient and contemporary philosophical sources.
