He rapidly began acquiring knowledge about the Roman Curia and develop connections with various individuals. While in Rome, Louis-Honoré became very ill, and Benjamin promised that, should his brother recover, he'd build a chapel to the Virgin Mary, which he did upon in return. It is the modern Notre-Dame-de-Grâce chapel. Upon his return in 1866 he was appointed to Université Laval's faculty, and soon thereafter got involved in one of numerous controversies that would pit him against Alexis Pelletier, a virulently polemic ultra-montane who would remain one of his staunchest opponents. This first clash was related to Frenchman Jean-Joseph Gaume's crusade to remove pagan authors from the classical curriculum, which Pelletier echoed in Canada. While in Rome, Pâquet had supported Elzéar-Alexandre Taschereau and Thomas-Étienne Hamel against him, and Pelletier retorted such vehement accusations that Bishop Charles-François Baillargeon sent a pastoral letter that threatened the anonymous accuser with canonical suspension. At the university, Pâquet taught a number of classes, and became dean of the faculty of theology in 1871, a position he'd maintain until 1879. His last five lectures in his 1871-1872 *Laws of the Nations* course specifically discussed the explosive topic of Liberalism. In class, he refuted the most radical form based on the arguments from various papal teachings, revealing himself a moderate ultra-montane and carefully avoiding to touch the more troublesome local aspects (the rise of the Liberal Party of Canada, which its opponents saw as "an anti-Catholic party"), primarily because "the term did not have the same meaning [in Canada] as in Europe." These teachings were seen by all as displaying "bulletproof orthodoxy", which didn't keep Pelletier from denouncing them on his own in newspapers and a pamphlet. These attacks proved fruitless, and the text was hailed in La Civiltà Cattolica as "the most faithful echo of Roman doctrines." A revised and corrected edition was issued in 1877 in Rome. Second trip to Rome In 1873 Pâquet's candidacy for the then Diocese of Kingston was successfully opposed. That same year he resigned, citing health issues. Then-rector Hamel allowed him one year in Europe to recover. Pâquet was granted money so he could eventually provide some services to the University. It didn't take long before Pâquet was again deeply involved in defending the University's interests in Rome, and one year turned into five. From Rome he became nothing short of a mastermind when it came to uncovering the events
