Britto is first known from a meeting of the bishops of Gaul in 374, held at
Valence on the
Rhône. Britto claimed there that
apostate Christians from the persecution under
Emperor Julian (361–363) could return to church under certain conditions. He was also a representative of the Church of Gaul to the
synod of Rome of 382, chaired by
Pope Damasus I. This meeting addressed a letter to the bishops of the East. Britto was the third signatory after by Pope Damasus and Bishop
Ambrosius. He was also at the court of the Roman emperor,
Maximus, in Trier for the trial of
Priscillian, who was accused of heresy and sorcery. It was here that he met
Martin of Tours and
Ambrose of Milan who had travelled to Trier and tried in vain to prevent the execution of Priscillian. Britto died 385 or 386. His grave is in
St. Paulinus' Church, Trier. He is venerated as a saint in the
diocese of Trier, where his
feast day is 6 May. ==References==
