He was born in Cappadocia around the year 170. He enthusiastically followed the lessons of the Alexandria School of Christian Education and studied under its most famous professors, such as Pantaenius and Clement of Alexandria. When he returned to his country, he declared his faith in Christ despite the risk of imprisonment during the persecution of Christians by the Roman Emperor Septimius Severus in the year 202 AD. At the end of the third century AD, he was elected Bishop of Cappadocia, and then he was put in prison for three years.

After his release from prison, he wanted to make a pilgrimage to Jerusalem. There, some jealous believers forced him to stay among them and assist their sheikh bishop, so he remained in Jerusalem after he heard a divine voice urging him to stay, so he remained in Jerusalem and became an assistant to its bishop. Then, on August 7, Saint Narcissus, Bishop of Jerusalem, died in the Lord. In the year 212, the people chose Saint Alexandros in the Church of Jerusalem to be its bishop after the death of his predecessor, Saint Narcissus. He sat in the chair for thirty-nine years. Throughout these years, he played an important role in maintaining peace between the churches and in establishing the faith.

He founded the first Christian library in Jerusalem, in which he collected the most important works in Christianity and the most valuable letters that the Fathers exchanged regarding the problems and needs of the Church. This library is considered the oldest Christian library. Eusebius, the author of the “History of the Church,” was able to access this library. In the year 215-216, Origen fled from Alexandria and took refuge in Caesarea Palestine as a result of the persecution ordered by Caracalla. The Bishop of Caesarea, Theoctistus, and the Bishop of Jerusalem, Alexandros, received him. They asked him, along with other bishops, to interpret the Holy Scriptures for the majority of believers, and he did so. Demetrius, Bishop of Alexandria, became angry and wrote to the bishops reprimanding them for deviating from the usual custom and allowing laymen to teach in the church. Demetrius ordered Origen to return to Alexandria. So he returned to it and continued his teaching and writing from the year 217 to 230. When he went to Greece and passed through Caesarea Palestine, its bishop celebrated him by ordaining him as a priest. This angered Demetrius, so he dropped him from the teaching job. In the year 231, the Empress brought him to Antioch, then he returned to Caesarea Palestine and settled there. A theological school arose around him. The most famous people who read about Origen were Gregory the Wonderworker and his brother Athendorus and Vermilian of Cappadocia.

When the persecution of Decius began in 249-251, the soldiers stopped him and sent him to Caesarea Palestine, where they threw him to the beasts to devour him. He cried out, saying: “Lord, if you want me now, let it be your will.” The monsters stopped licking his feet. Then the soldiers threw him into prison and tortured him until he died. The church celebrates him on the twelfth of December and on the 16th of May.
