Vieyra’s tastes inclined him to abandon his studies and to devote himself entirely to the Indians; but his far-seeing superiors discerned too well his remarkable talents to permit them to be devoted entirely to such a purpose. After some years spent in ministering amongst Indians and negroes, and in the acquisition of the _Tupi_ language, for the benefit of the former, and of that of _Angola_, for the benefit of the latter, he was, in 1635, ordained a priest. He now lectured on theology at _Bahia_, and, sometime later, he accompanied the agent sent to Portugal to congratulate the King on the recovery of his rights. Arriving at Peniche in company of _Dom_ Fernando Mascarenhas, whose brother had adhered to the king of Castile, he was arrested by the people and narrowly escaped being put to death. The populace were, however, persuaded to deliver him over to justice. Reaching Lisbon as a supposed criminal, he obtained an audience of the King, upon whom his remarkable talents produced an instant effect. He was appointed preacher to Joam IV., who continued ever afterwards to regard him with the affection of a father to a son. In his sermons he expressed himself with such freedom as well as eloquence that he was at one time brought under the notice of the Inquisition. [Sidenote: 1652.] The favour which Vieyra enjoyed at court created the jealousy even of his own order, and it was once feared that they were about to expel him. In anticipation of this, he was offered by the King a bishopric, which offer, however, was declined. The jealousy of Vieyra’s superiors was at length, happily, removed, and he was employed during several years in the most important diplomatic service, including a mission to the Hague at a critical period. About the year 1652, after the _Brazil_ Company had been established owing to his representations, the fleet of which Company was the means used by Fernandes to complete the reduction of _Recife_, the thoughts of the Jesuit Father began to be powerfully attracted towards the land of his early education. From the possession of his special gifts, more particularly his knowledge of the Indian and _Angola_ languages, he probably felt that there was work to be done which he was likely to perform better than any living man. But there was a strong obstacle in the way. This was the favour with which he was regarded both by King Joam and by his son, Prince Theodosio, from both of whom he felt it would be useless to solicit permission to depart on his proposed voyage.
