Juan X
Gauzelin was born to noble Frankish parents. He first served as part of notaries in the French kingdom from 913 to circa 919 which later led to King Charles naming him as the Bishop of Toul; Pope John X confirmed the appointment and he received his episcopal consecration on 17 March 922 from Ruotger. Gauzelin promoted discipline for the monasteries and for diocesan priests and tried to defend the church against secular threats.
