Abstract

The present study aims to investigate the theological foundation of Arnold Janssen's relationship with the Holy Spirit through the dynamism of that Spirit and its receptivity as "communication" of that Spirit, who unites the Father through the Son, the Incarnate Word, in such a way that its effects urge in love tireless missionary service both at a personal and a community level, from interior to external expansion, based on theological certainty and mystical experience which is of great relevance in today's adverse context.
