The Evangelish-methodistische Kirche im Deutschland (UMC in Germany) has recently published two profiles of Methodist mission leaders. Both profiles (written in German) are well worth reading for understanding the character of Methodist mission engagement in the 20th century and early 21st century.
The EmK website published a nice biography of Philip Potter on the occasion of the 100th anniversary of his death. Potter, who was born in Dominica, went on to serve as the Secretary of the British Methodist missionary society, the Director of the Commission on World Mission and Evangelism of the World Council of Churches (WCC), and ultimately the General Secretary of the WCC. As Klaus Ulrich Ruof writes in the profile, "Potter shaped the ecumenical movement like no other in the second half of the last century."
Emk-Weltmission (the German Methodist mission agency) published an obituary of former long-time EmK-Weltmission Treasurer Walter Volz. The obituary, written by Thomas Kemper, gives a sense of how one person can live out the principles of mission through faithful service. As Kemper writes, "Mission is friendship. Mission is relationship. Mission is sharing life. Walter Volz lived it."
