Eusebius of Caesarea, also known as Eusebius Pamphilus, was a Greek or Palestinian historian of Christianity, exegete, and Christian polemicist. In about AD 314 he became the bishop of Caesarea Maritima in the Roman province of Syria Palaestina. Together with Pamphilus, he was a scholar of the biblical canon and is regarded as one of the most learned Christians during late antiquity. He wrote Demonstrations of the Gospel, Preparations for the Gospel and On Discrepancies between the Gospels, studies of the biblical text. As "Father of Church History", he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs. He also produced a biographical work on Constantine the Great, the first Christian Roman emperor, who was augustus between AD 306 and AD 337.
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 to have opposed both the Valentinians and Gnostics during his papacy. He is considered a saint by the Catholic Church and the Eastern Orthodox Church with a feast day in 11 July, but it is unclear if he died as a martyr.

Year 315 (CCCXV) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantinus and Licinianus. The denomination 315 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Flavia Julia Helena, also known as Helena of Constantinople and Saint Helena, was an Augusta of the Roman Empire and mother of Emperor Constantine the Great. She was born in the lower classes traditionally in the Greek city of Drepanon, Bithynia, in Asia Minor, which was renamed Helenopolis in her honor, though several locations have been proposed for her birthplace and origin.
The calendar of saints is the traditional Christian method of organizing a liturgical year by associating each day with one or more saints and referring to the day as the feast day or feast of said saint. The word "feast" in this context does not mean "a large meal, typically a celebratory one", but instead "an annual religious celebration, a day dedicated to a particular saint".
An apostolic see is an episcopal see whose foundation is attributed to one or more of the apostles of Jesus or to one of their close associates. In Catholicism, the phrase "The Apostolic See" when capitalized refers specifically to the See of Rome.
In the Christian liturgical calendar, there are several different Feasts of the Cross, all of which commemorate the cross used in the crucifixion of Jesus. 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. In Western Catholicism, Eastern Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, Lutheranism and Anglicanism the most common day of commemoration is 14 September, or 27 September in churches still using the Julian calendar.

During the reign of the Roman Emperor Constantine the Great, 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.
