Uz primjenu imagološke analitičke metode, a na temelju kontroverzijskih katekizama sjevernohrvatskih franjevaca (Bačić, Vilov, Pavić) iz 18. stoljeća, rad se bavi fenomenom konstituiranja konfesionalnoga (katoličkoga) identiteta i (pravoslavnoga) alteriteta kao središnjega dijela problematike. Konfesionalna se drugost stoga nastoji jasnije definirati analizom suodnosa autopredodžbi i heteropredodžbi na relaciji katolici – pravoslavci u 18. stoljeću, ponajprije na području Slavonije. Spomenuti su franjevci, kao pripadnici budimskoga kulturnoga kruga, pisali djela teološke kontroverzije na narodnome jeziku koja je u 18. stoljeću bila izraz osobitoga teološkoga interesa među (slavonskim) vjerskim polemičarima. Sva su trojica franjevaca tijekom svoga pastoralnoga rada zasigurno bila u kontaktu s pravoslavnim kršćanima, no glavni recipijenti franjevačkih kontroverzističkih tekstova nisu pravoslavni kršćani, nego katolici kojima su takva djela namijenjena kao praktična pomagala u vjerničkome dijalogu s pravoslavnim kršćanima. Nije stoga slučajno što franjevci u svoje katekizme umeću kontroverzističke dijelove (iako im to nije glavna svrha). Ni Bačić, ni Vilov, a ni Pavić ne pišu prave vjerske polemike, poput onih isusovačkih na latinskom (Pejačević, Werntle, Šimunić), pa i hrvatskom jeziku (Kanižlić), ali su njihovi katekizmi uvelike obilježeni i određeni kontroverzijskom tematikom/problematikom. Posebna im je vrijednost i u tome što su pisani narodnim jezikom koji je, ipak, rijetkost za polemički žanr u 18. stoljeću, obilježen visokim stilom (latinskim jezikom), složenom teološkom i crkvenopovijesnom tematikom i upućenošću obrazovanim recipijentima. Katekizmi spomenutih franjevaca otkrivaju nasljedovanje tendencija i preokupacija posttridentskoga razdoblja katoličke obnove te su osebujan i važan pokazatelj smjera vjerskopolemičke literature u širem kontekstu književne kulture u osamnaestostoljetnoj Slavoniji. Using the imagological analytical method, based on controversial catechisms of the northern Croatian Franciscans (Bačić, Vilov, Pavić) from the 18th century, the paper addresses the phenomenon of constituting the confessional (Catholic) identity and (Orthodox) alterity as the central part of the issue. Therefore, the paper aims to clarify the confessional otherness through the analysis of the interrelationship of auto-images and hetero-images between Catholic and Orthodox Christians in the 18th century, primarily in Slavonia. The mentioned Franciscans, as members of the cultural circle of Buda (Budim), wrote works of theological controversy in the vernacular, which was an expression of particular theological interest among the (Slavonian) religious polemicists in the 18th century. During their pastoral work, all three Franciscans must have been in contact with Orthodox Christians, however, the target readers of the Franciscan controversial texts were not the Orthodox Christians but Catholics for whom such works were intended as a practical aid for religious dialogue with the Orthodox Christians. Therefore, it is not by accident that the northern Croatian Franciscans inserted controversial parts in their catechisms (although it is not their main purpose). Neither Bačić, nor Vilov, nor Pavić wrote true religious polemics, like those of the Jesuit written in Latin (Pejačević, Werntle, Šimunić) as well as Croatian (Kanižlić), but their catechisms are largely characterized and determined by controversial thematic/problematics. They are especially valuable because they are written in the vernacular, which is rare in the polemic genre of the 18th century, characterized by the grand style (Latin language), complex theological and church history themes, as well as orientation towards educated recipients. The catechisms of the above-mentioned Franciscans reveal a legacy of tendencies and preoccupations of the post-Tridentine era of the Catholic Reformation and are also a peculiar and important indicator of the direction of religious polemic literature within the scope of a wider context of literary culture of the 18th century Slavonia.
