He traveled to Tanzania with no second thoughts about the risks and trouble, in order to undertake the supervision of the construction of the Holy Church of St. Ioannis the Theologian at the village of Imbogo. He is an outright example of self-denial and self-sacrifice because, despite him being seventy years old, he made the long and toilsome journey with the sole aim of selfless contribution to the great “front” called Mission.
