During the 14th century, the facilitation of trade and communications throughout Eurasia caused the Mongols to unintentionally accelerate the spread of bubonic plague in southwestern China, causing the demise of Christianity. However, in the sixteenth century, as the world economy began to stabilize, Roman Catholic missionaries made their way across Asia to win proselytes and found Christian churches, monasteries, and communities using European science, technology, and mechanics to whet Chinese and Japanese. curiosity. Without any “off-limits” adaptation of proselytism, it ensured the rise of Christianity in Asia after Europe's demographic recovery. Missions led by prominent Jesuits, such as Matteo Ricci, made Christianity accessible and more attractive to Asia's culturally and ethnically diverse population through language and technology, while St. Francis Xavier, another missionary, took a similar approach but he concentrated more on the arguments posed against Christianity. Matteo Ricci, an Italian Jesuit priest, traveled from Portugal in an attempt to persuade China to adopt Christian doctrine. Ricci and his companions were the first missionaries to make significant progress in China during the 17th century. Although he failed to evangelize all of China, his method of introducing Christianity created a significant cultural impact. These impacts required him to learn and be familiar with the Chinese language. Upon arriving in China, Ricci learned "to speak the native language and read their books" (Ricci, 271) which helped him communicate with the locals about European science, technology, and mechanics. The document entitled “A speech from the Kingdom of China” by Matteo Ricci…… in the center of the paper……to convert people to Christianity. Although some methods were different, most of the factors underlying proselytization, such as language and knowledge, were emphasized, which made Christianity more attractive and accessible to Asia's culturally and ethnically diverse population.
