Justus Baronius Calvinus
Justus Baronius Calvinus was a German theologian, a Roman Catholic convert and apologist.Life
He was born of Calvinist parents and educated at Heidelberg, where he took a course in theology. His study of the Church Fathers inclined him towards Catholicism and finally led him to Rome. There he was kindly received by Cardinal Bellarmine, Cardinal Baronius, and Pope Clement VIII. His gratitude to Baronius caused him to add that cardinal's name to his own.
On his return to Germany he became a Catholic and a staunch defender of his faith. In his "Apologia" he gives the reasons for his conversion and in his "Praescriptionum adversus haereticos... Tractatus" he appeals to the Fathers in support of the truth of Catholicism.
