ANDRADA DE PAYYA, DIOGO. — Distinguished Portuguese theologian, born in Coimbra in 1528, died in Lisbon in 1575. He taught at the University of his native city. In 1561 he was sent by King Sebastião of Portugal, as his theologian, to the Council of Trent.
He published seven volumes of sermons in Portuguese, not entirely free from censure, since, among other things, the author admits the salvation of the ancient philosophers by virtue of a vague knowledge of the Redeemer, as well as a book entitled: De Conciliorum auctoritate. But what made him most famous was his activity against the Protestants, and particularly against Martin Chemnitz, in two works: Orthodoxarum explicationum libri decem (Venice 1564), and Defensio Tridentinae Fidei Catholicae (Lisbon 1578).
