Returning to France he preached for six months in his native town, and went to Orléans, 1560, where, after being a teacher of Hebrew, he was ordained minister of the local Reformed church in 1561.
He then left with his family to Montargis, where he was protected by the duchess of Ferrara until the king of France demanded the expulsion of all Huguenots.
Here he was charged with teaching Calvinistic and Zwinglian heresies; his reply was an affirmation of his Lutheran belief.
In November 1572, he was able to return to his father at Montbéliard, but Lutheran intolerance again drove him out, and he accepted a call to the French refugees at Basel.
[3] As an author he was prolific, producing 33 works, listed in F. W. Cuno, Daniel Tossanus (Amsterdam, 1898).
