November 1893. After the Portuguese left Oman in the mid-seventeenth century, this is considered to be the most significant interaction Omanis have had with Christianity. Their objective was to evangelize the Muslim population of the Arabian Peninsula through the teachings of the Bible and other Christian literature. As such, a printing press was opened in Muscat in 1900 with the intention of printing polemical and devotional literature. One of the pieces printed, "Jesus or Mohammed", portraying the Prophet Mohammed as sinful and Jesus Christ as sinless. Because their methodology was through the spread of literature, missionaries also provided educational services to Omanis. They would teach literacy through teaching the Bible, which they translated into Arabic. Missionary teachers also taught children other subjects, like math and writing. Missionaries set up medical facilities, as well. The obvious reason for this was delivering the power of Christ through healing, but it was also an additional chance to evangelize the population. Omanis saw the missionary doctors in more favorable terms than priests and educators, therefore allowing them access to spaces usually forbidden to missionaries. Thus, while there was no requirement for doctors to evangelize, they oftentimes took advantage of their privileged position among Omanis to proselytize. For more rural populations that had no access to modern medical services, this could entice them to convert.
