This study celebrates the 40th anniversary of the International Association for Mission Studies (IAMS) which took place in 2012, during the thirteenth conference of the association held in Toronto (Canada). IAMS brings together people interested in the mission of the Church and misisonaries that are actively involved in this field. As an international missionary association, IAMS reunites different theological and ecclesial traditions. Theological views are consonant with the confessional theologies and the research tasks of a confession or missiologist.
