St. Boniface I was born in Rome circa 350. Ordained a priest, he became papal legate to Constantinople circa 405 for Pope Innocent I. St. Boniface was elected the 42nd pope in 418. Anti-pope Eulalius opposed Pope Boniface, so the Roman emperor exiled both men from Rome in an effort to keep peace. After Eulalius tried to return against the will of the emperor, he was exiled again and St. Boniface was declared pope. The saint strongly opposed Pelagianism. St. Boniface I died Sept. 4, 422, in Rome.
