Input: Consider Input: Question: How old was Bartolome de las Casas when he was recalled from his mission? Passage:On his second visit to Guatemala, in 1537, friar Bartolome de las Casas, O.P. wanted to employ his new method of conversion based on two principles: 1) to preach the Gospel to all men and treat them as equals, and 2) to assert that conversion must be voluntary and based on knowledge and understanding of the Faith. It was important for Las Casas that this method be tested without meddling from secular colonists, so he chose a territory in the heart of Guatemala where there were no previous colonies and where the natives were considered fierce and war-like. Because of the fact that the land had not been possible to conquer by military means, the governor of Guatemala, Alonso de Maldonado, agreed to sign a contract promising that if the venture was successful he would not establish any new encomiendas in the area. Las Casas's group of friars established a Dominican presence in Rabinal, Sacapulas and Cobán, reaching as far as Chahal and including Cubulco. Through the efforts of Las Casas' missionaries the so-called "Land of War" came to be called "Verapaz", "True Peace". Las Casas's strategy was to teach Christian songs to merchant Indian Christians who then ventured into the area. In this way he was successful in converting several native chiefs, among them those of Atitlán and Chichicastenango, and in building several churches in the territory named Alta Verapaz. These congregated a group of Christian Indians in the location of what is now the town of Rabinal. In 1538 Las Casas was recalled from his mission by Bishop Francisco Marroquin who wanted him to go to Mexico and then on to Spain in order to seek more Dominicans to assist in the mission.
