One of the main challenges faced by the missionaries and their US supporters was the renewal of their short-term visas. The State Department repeatedly urged its Italian counterparts to consider issuing permanent or long-term residence permits, hoping to eliminate one of the most contentious points of the ongoing dispute. While the Italian Ministry of Foreign Affairs was generally sympathetic to these proposals and sought to accommodate Washington’s requests, it faced significant resistance from Mario Scelba, the inflexible interior minister, as well as repeated pressures from the Vatican. The Vatican followed the matter with interest and concern, viewing the presence of Protestant missionaries as a potential threat to Italy’s Catholic identity and spiritual unity. Catholic propaganda leaned heavily on familiar anti-Protestant tropes, portraying Protestantism as a foreign import, threatening the country’s cohesion and spiritual unity, which, it was argued, was essential to counter the Communist threat. The visa issue became a constant point of contention, resolved only through temporary solutions and case-by-case renewals. Meanwhile, the missionaries frequently clashed with Italian authorities, who sporadically (and inconsistently) harassed them by shutting down preaching halls or preventing access to their facilities.
