Pope Miltiades, also known as Melchiades the African, was the bishop of Rome from 311 to his death on 10 or 11 January 314. It was during his pontificate that Emperor Constantine the Great issued the Edict of Milan (313), giving Christianity legal status within the Roman Empire. The pope also received the palace of Empress Fausta where the Lateran Palace, the papal seat and residence of the papal administration, would be built. At the Lateran Council, during the schism with the Church of Carthage, Miltiades condemned the rebaptism of apostatised bishops and priests, a teaching of Donatus Magnus.
Pius I was the bishop of Rome from c. 140 to his death c. 154, according to the Annuario Pontificio. His dates are listed as 142 or 146 to 157 or 161, respectively.

He is considered a saint by the Catholic Church with a feast day in 11 July, but it is unclear if he died as a martyr.
Pope Sylvester I was the bishop of Rome from 31 January 314 until his death on 31 December 335. He filled the See of Rome at an important era in the history of the Western Church, though very little is known of his life.

The Feast of the Holy Cross, or Feast of the Cross, commemorates the cross used in the crucifixion of Jesus. In the Christian liturgical calendar, there are several different celebrations which honor and celebrate the cross used in the crucifixion. Unlike Good Friday, which is dedicated to the passion of Christ and the crucifixion, these feast days celebrate the Cross itself, as the sign of salvation. It is chiefly celebrated by Roman Catholics, Eastern Orthodox, Oriental Orthodox, Old Catholics, Lutherans and Anglicans, and to a lesser extent by Presbyterians, Methodists and Baptists. The most common day of commemoration is September 14th for Churches that use the Gregorian calendar and September 27th for Churches that use the Julian calendar, Ge'ez calendar, or Coptic calendar.

During the reign of the Roman emperor Constantine the Great (306–337 AD), Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have often argued about which form of early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or, as claimed by Eusebius of Caesarea, encouraged her to convert to the faith he had adopted.
