A meeting between atheistic socialism and theistic Christianity is difficult, but it is not impossible. The key is to exercise the Christian ethic of love for one's enemy and consequently move the atheist. This method, through the employment of Christian ethics, is effective in its ability to allow understanding to occur between the two parties. This type of occurance is non other than a meeting with athiests through Christian Diaconia. Even under communist rule, the former Eastern block hosted large Christian rallies. Hungary's Budapest was a host to the Lutheran Church's world-wide conference and East Germany hosted huge celebratory events, with outside guests, in commemoration of the 500th anniversary of the Reformer Luther's birth. These episodes are memorable and momentous events that occured under atheist communist control. This paper investigates how such events were made possible and addresses the appropriate history lessons that should be taken away. Afterwards, the issue of how the Korean Church should approach the matter of the upcoming Pyongyang rally is addressed. Particularly, the manner in which the German Church engaged East Germany in Diaconia(service) is historically explored and applied. How the Christian ethic of love was made specific and tangible is additionally investigated. In other words, the type of approach and philosophy that is appropriate in dealings with socialism, in accordance to God's love as was given by Christ on the cross, will be attempted to make clear. The research will primarily consist of a practical investigation into one of today's most salient issues, that is, in what manner and in accordance to what ethics the Korean Church should approach the 2007 Pyongyang Rally, the Church's 100 year anniversary of the great revival. In turn, the hope is to envision a socially ethical philosophy for the Korean Church's expression of Diaconia.
