Our testimony:
We are Tiago and Ariane, married and serving the Lord together through ministry, training, and missions across South America. Through years of pastoral ministry (17 years), theological training (8 years), and missionary service (10 years), the Lord has shaped our calling to equip pastors and church leaders with the Scriptures, helping strengthen local churches and encourage faithful biblical ministry.
We have had the privilege of serving churches and leaders in several regions of South America, including the Amazon, Uruguay, and Bolivia, and also Mozambique. We continue to pursue opportunities to train leaders specially in places where access to solid theological training is limited. Our desire is to serve local churches by strengthening its leaders, so that the gospel may continue to advance and healthy churches may grow throughout the region.
