This research analyzes the speaking in tongues in Mark 16.15 to 18 and the diachronic process of theological evolution of speaking in tongues in the canonical literature, where speaking in tongues: 1. Initially would be a free and community experience of glossolalia ; 2. It was standardized by Paul in 1 Corinthians, but keeping their glossolalia characteristics; 3. theologized in Acts being linked to spread of the Gospel, however, being experienced now by evangelizing (Acts 2 equal xenoglossy), then by evangelized (Acts 10:19 equal glossolalia); 4. To finally be thouth theologically as a sign that accompanies the itinerant missionaries in evangelization (Mark 16.15 to 18). Understand the diachronic of speaking in tongues is important to improve the dialogue between this last theological proposal received by the Church s tradition, and will serve as a reading filter and theological thought of training on speaking in tongues for those who read or hear the synchronic narrative through the allocation of the canonical Gospel of Mark (promise of Jesus), Acts of the Apostles (early Church) and the First Letter of Paul to the Corinthians (ecclesiastical explanation).
