After working as a tax optimization advisor, Matthieu Jasseron decided to leave Paris and his job, which was not really meaningful to him, to become a volunteer at Secours Catholique. There he met God and decided to become a priest of the diocese of Sens-Auxerre. Today a parish priest in Joigny, Yonne, he is known for his videos with a free and off-beat tone on TikTok, a network on which he has more than a million subscribers.
