Saint Leo the Great for having written the letter to Flavian

Among the ranks of the early Church's faithful shepherds, few acts of loyalty resonate as profoundly as the gratitude expressed by the bishop of Grenoble. This holy prelate, known as Cérat, stands not for a life of miraculous spectacle, but for a moment of profound ecclesiastical solidarity. His name is preserved in history primarily through a single, significant gesture: the expression of thanks to Pope Saint Leo the Great. This act anchors him firmly within a critical era of doctrinal defense and unity, marking him as a guardian of orthodoxy in the region of Burgundy.
