Father Xavier was very desirous of returning to Travancore; but the winds blew so contrary, that they always drove him from the coast.  By this he judged that God had called him to some other place; and thereupon formed a resolution of carrying the light of the gospel from isle to isle, and from kingdom to kingdom, even to the utmost limits of the East.  The news he heard, during his navigation, caused him suddenly to cast his thoughts on an island situate under the equinoctial, betwixt the Moluccas and Borneo, stretched in length two hundred leagues from north to south, and divided into sundry kingdoms, called by the geographers Celebes, by the historians Macassar, from the names of the two capital cities, of the two principal kingdoms; as to the rest, well peopled, and abounding in all sorts of riches.

It was related to him, that about the year 1531, two brothers, both idolaters, as were all the inhabitants of Macassar, going on their private business to Ternate, the chief of the Moluccas, had some conference, relating to religion, with the governor, Antonio Galvan, a Portuguese, one of the most famous warriors of his age, and celebrated in history both for his piety and valour:  that having learnt from him the vanity of their idols, they embraced the Christian faith, and at their baptism took the names of Antonio and Michael:  that being returned into their country, they themselves taught publicly the faith of Jesus Christ:  that all their countrymen, with one accord, sent their ambassadors to the governor of Ternate, desiring him to send them some to instruct them in the principles of faith; and that the heads of this embassy were the two brothers, known to Galvan:  that these ambassadors found a very kind reception; and that for want of a priest, Galvan gave them a soldier for their teacher, whose name was Francis de Castro; a man knowing in religion, and of exemplary piety.  In conclusion, that Castro, who was thus chosen to instruct that people, embarking for Macassar, was driven by a tempest another way.

Besides this, Xavier was likewise informed, that not long before, a Portuguese merchant, called Antonio Payva, going to Macassar in the name of Ruys Vaz Pereyra, captain of Malacca, for a ship’s lading of sandal, a precious wood growing in that island, the king of Supa, which is one of the kingdoms of Macassar, came in person to see him, and asked divers questions relating to the Christian faith:  that this honest merchant, better acquainted with his traffic than his religion, yet answered very pertinently, and discoursed of the mysteries of faith after so reasonable a manner, that the king, then threescore years of age, was converted, with all his family and court:  that another king of the same island, called the king of Sion, followed his example; and that these two princes, who were solemnly baptized by the hand of Payva, not being able to retain him with them, desired him to send them some priests, who might administer the sacraments, and baptize their subjects.
