For someone claiming that had studied the Sengoku era , it ' s pity that you didn ' t even know what Hideyoshi Toyotomi said to Gaspar Coelho as I wrote in Japanese above . At least from the Japan ' s political leader ' s point of view , the missionaries were on the same boat with these traders , as they came to Japan often together . Spanish and Portuguese Jesuits acted as merchant priests wherever they went . They converted the locals , entitled the converted local lords as the only trade partners , lend funds and arms , and instigated them to attack other political rivals to spread the word of the Church , only to make tribes and kingdoms get weakened within and eventually conquer the whole . That ' s what happened to Africa , the New World , and many parts of Asia . You like it or not , the church had accepted slavery , and these Jesuits owned slaves . If this is your first time to see these historical facts , I encourage you to read more books .
