Pope St. Sixtus II (d. 258 A.D.) became the Roman Pontiff in the year 257 A.D. His early life is uncertain, and he is mentioned by name in the Roman Canon of the Mass. He helped mend the relationship between Rome and the Eastern and African churches over the problem of the rebaptism of converted heretics, a controversy which threatened schism. St. Sixtus II, a peaceful man, restored friendly relations and maintained unity. However, he served as Holy Father for only one year due to the persecution of Christians by Roman Emperor Valerian. As a result, Pope St. Sixtus II was suppressed and forbidden to celebrate the Holy Sacrifice of the Mass. He continued to worship in secret in defiance to the unjust law, and while offering Mass in a cemetery chapel he was ambushed and beheaded by Roman soldiers. His feast day is August 7th.
