Christian humanists

Théodore André Monod (9 April 1902 – 22 November 2000) was a French naturalist, humanist, scholar and explorer.

Ulrich von Hutten (21 April 1488 – 29 August 1523) was a German knight, scholar, poet and satirist, who later became a follower of Martin Luther and a Protestant reformer.
By 1519, he was an outspoken critic of the Roman Catholic Church. Hutten was a bridge between the Renaissance humanists and the Lutheran Reformation.
He was a leader of the Imperial Knights of the Holy Roman Empire along with Franz von Sickingen. Both were the leaders in the Knights' Revolt.

Charles Pierre Péguy (French: [ʃaʁl peɡi]; 7 January 1873 – 5 September 1914) was a French poet, essayist, and editor. His two main philosophies were socialism and nationalism; by 1908 at the latest, after years of uneasy agnosticism, he had become a believing (but generally non-practicing) Roman Catholic.
From that time, Catholicism strongly influenced his works.
