The Christian faith was first introduced into Japan in the sixteenth century by Jesuit and later by Franciscan missionaries. By the end of that century, there were probably about 300,000 baptized believers in Japan.
Unfortunately, this promising beginning met reverses, brought about by rivalries between different groups of missionaries and political intrigues by the Spanish and Portuguese governments, along with power politics among factions in the Japanese government itself. The result was a suppression of Christians.
The first victims were six Franciscan friars and twenty of their converts, who were crucified as Nagasaki on 5 February 1597. After a short interval of relative tolerance, many other Christians were arrested, imprisoned for life, or tortured and killed; and the Church was totally driven underground by 1630. However, when Japan was re-opened to Western contacts 250 years later, it was found that a community of Japanese Christians had survived underground, without clergy, without Scriptures, with only very sketchy instructions in the doctrines of the faith, but with a firm commitment to Jesus as Lord. (I remind you that 250 years is a long time -- 250 years ago Americans were loyal subjects of King George II.)
Prayer (traditional language)
O God our Father, who art the source of strength to all thy saints, and who didst bring the holy martyrs of Japan through the suffering of the cross to the joys of life eternal: Grant that we, being encouraged by their example, may hold fast the faith that we profess, even unto death; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever.Prayer (contemporary language)
O God our Father, source of strength to all your saints, who brought the holy martyrs of Japan through the suffering of the cross to the joys of life eternal: Grant that we, being encouraged by their example, may hold fast the faith we profess, even to death itself; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever.
