Origen in the context of "The True Word"

The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers who established the intellectual and doctrinal foundations of Christianity. The historical period in which they worked became known as the Patristic Era and spans approximately from the late 1st to mid-8th centuries, flourishing in particular during the 4th and 5th centuries, when Christianity was in the process of establishing itself as the state church of the Roman Empire.

For many denominations of Christianity, the writings of the Ante-Nicene Fathers, Nicene Fathers and Post-Nicene Fathers are included in Sacred Tradition. As such, in traditional dogmatic theology, authors considered Church Fathers are treated as authoritative for the establishment of doctrine. The academic field of patristics, the study of the Church Fathers, has extended the scope of the term, and there is no definitive list. Some, such as Origen and Tertullian, made major contributions to the development of later Christian theology, but certain elements of their teaching were later condemned.

The Jewish–Christian Gospels were gospels of a Jewish Christian character quoted by Clement of Alexandria, Origen, Eusebius, Epiphanius, Jerome and probably Didymus the Blind. All five call the gospel they know the "Gospel of the Hebrews", but most modern scholars have concluded that the five early church historians are not quoting the same work. As none of the works survive to this day, attempts have been made to reconstruct them from the references in the Church Fathers. The majority of scholars believe that there existed one gospel in Aramaic/Hebrew and at least two in Greek, although a minority argue that there were only two, in Aramaic/Hebrew and in Greek.

In the standard edition of Schneemelcher, he creates three different Jewish–Christian gospels by dividing up the references in the church fathers. Schneemelcher uses the following working names for the three proposed gospels:

According to the New Testament, a woven crown of thorns (Ancient Greek: στέφανος ἐξ ἀκανθῶν, romanized: stephanos ex akanthōn or ἀκάνθινος στέφανος, akanthinos stephanos) was placed on the head of Jesus during the events leading up to his crucifixion. It was one of the instruments of the Passion, employed by Jesus' captors both to cause him pain and to mock his claim of authority. It is mentioned in the gospels of Matthew (Matthew 27:29), Mark (Mark 15:17) and John (John 19:2, 19:5), and is often alluded to by the early Church Fathers, such as Clement of Alexandria, Origen and others, along with being referenced in the apocryphal Gospel of Peter.

Since around 400 AD, a relic has been venerated as the crown of thorns. Louis IX acquired it in 1239 from the emperor Baldwin Il, who was financially in debt due to heavy military expenses. Louis IX built the Sainte-Chapelle as a monumental reliquary to house the relic. Transferred to the French National Library during the Revolution of the 18th century, the crown of thorns has been displayed at Notre-Dame de Paris since 1804. The crown is made of reeds, formed into a circle and attached with reed fasteners. On 15 April 2019, it was rescued from a fire and moved to the Louvre Museum. In December of 2024, a ceremony marking the relic's return to Notre Dame Cathedral was led by a procession attended by members of the Equestrian Order of the Holy Sepulchre. Veneration of the crown of thorns takes place every first Friday of the month from 3 pm to 5 pm.

Throughout the fifth century, Hellenistic-Eastern political systems, philosophies, and theocratic Christian concepts had gained power in the Greek-speaking Eastern Mediterranean due to the intervention of important religious figures there such as Eusebius of Caesarea (c. 260 – c. 339) and Origen of Alexandria (c. 185 – c. 253) who had been key to developing the constant Christianized worldview of late antiquity.

By the 6th century, such ideas had already influenced the definitive power of the monarch as the representative of God on earth and of his kingdom as an imitation of God's holy realm. The Byzantine Empire was a multi-ethnic monarchic theocracy adopting, following, and applying the Orthodox-Hellenistic political systems and philosophies. The monarch was the incarnation of the law—nomos empsychos—and his power was immeasurable and divine in origin insofar as he channeled God's divine grace, maintaining what is good. He was the ultimate benefactor, caretaker, and saviour of the people: Evergétis, Philanthrōpía, and Sōtēr, anointed with all power, upholding the divine laws since he ought to emulate Christ first (christomimetes) in all of his divine, pious, loving orthodox attributes to all by being his earthly presence.

Titus Flavius Clemens, also known as Clement of Alexandria (Ancient Greek: Κλήμης ὁ Ἀλεξανδρεύς; c. 150 – c. 215 AD), was a schematic Christian theologian and philosopher who taught at the Catechetical School of Alexandria. Among his pupils were Origen and Alexander of Jerusalem. A convert to Christianity, he was an educated man who was familiar with classical Greek philosophy and literature. As his three major works demonstrate, Clement was influenced by Hellenistic philosophy to a greater extent than any other Christian thinker of his time, and in particular, by Plato and the Stoics. His secret works, which exist only in fragments, suggest that he was familiar with pre-Christian Jewish esotericism and Gnosticism as well. In one of his works he argued that Greek philosophy had its origin among non-Greeks, claiming that both Plato and Pythagoras were taught by Egyptian scholars.

Clement is usually regarded as a Church Father. He is venerated as a saint in Coptic Christianity, Eastern Catholicism, Ethiopian Christianity, and Anglicanism. He was revered in Western Catholicism until 1586, when his name was removed from the Roman Martyrology by Pope Sixtus V on the advice of Baronius. The Eastern Orthodox Church officially stopped any veneration of Clement of Alexandria in the 10th century. Nonetheless, he is still sometimes referred to as "Saint Clement of Alexandria" by both Eastern Orthodox and Catholic authors.

Christian apologetics (Ancient Greek: ἀπολογία, "verbal defense, speech in defense") is a branch of Christian theology that defends Christianity.

Christian apologetics have taken many forms over the centuries, starting with Paul the Apostle in the early church and Patristic writers such as Origen, Augustine of Hippo, Justin Martyr and Tertullian, then continuing with writers such as Thomas Aquinas, Duns Scotus, William of Ockham and Anselm of Canterbury during Scholasticism.
