Many ancient societies were deeply influenced by Graeco-Roman Civilization, including early Judaic culture. The exchange between them produced important thinkers in Judaism, among them the philosopher Philo. He is perhaps the most important representative of Hellenistic Judaism whose works had a decisive influence on later Christian thinkers.

The Life of Philo

The exact date of Philo’s birth is not known, but it may have been about 20 BC. He was born into an influential family in Alexandria, Egypt, home at that time to one of the largest Jewish communities in the diaspora. His brother went on to become one of the wealthiest men in the city and even had connections with the imperial family during the reigns of Nero and Claudius.

Philo was brought up in a pious Jewish household and would have studied the Bible and Jewish scholarly works. Alexandria was, at the time, a cultural melting pot of Greeks, Jews and Egyptians. Thus, Philo was deeply influenced by Greek culture and was a student of Hellenic philosophy. He was also a Roman citizen and could speak and read Greek, as was the case with St. Paul, with whom he has some affinities. 

Philo was a devoted Jew and visited the Second Temple in Jerusalem at least once in his life. The only event that we know of in any detail is his role in an embassy to the infamous emperor Caligula. Rome’s Prefect in Egypt had ordered the Jews to worship Caligula as god, part of an empire-wide imperial cult. This, of course, was contrary to the strict monotheism of the Jews. The order also came at a time of conflict between the Greeks and the Jews in the city of Alexandria. In 38 AD, many Jews were killed in the city in what was possibly the first-known pogrom.


The Alexandrine Jewish community elected Philo, who was very well-respected, to lead a delegation to Rome and to plead with the Emperor to rescind the Prefect’s orders. Miraculously, Philo was able to persuade Caligula not to force the Jews to worship him or to set up his image in their temples. It is believed that Philo died about 50 AD.

The Theology of Philo

Philo was deeply influenced by Plato and like Plato, he believed that a life of contemplation was superior. The Alexandrine thinker was also influenced by the Stoics, Aristotle and the Cynics. Philo was something of a mystic, believing that a transcendent god could be known by intuition.  He also believed that certain numbers, such as seven, had particular religious significance.

Philo believed the purpose of existence was to strive to know god. He held that a supreme being had implanted in humans an innate love of him, allowing humans to achieve a personal union with the divine.

Philo also believed that reason and religion were not incompatible. He used the concept of Logos, or reason, in a new way. It had long been argued that the Logos referred to the rational ordering of the universe. However, Philo argued that Logos, or reason, was begotten of god and was associated with him. In some of Philo’s works Logos is the mediator between the human mind and the divine. He believed that using reason to understand the world also allowed humans to comprehend the transcendent. The Alexandrine thinker also believed that fate could be suspended, allowing miracles to occur. Unfortunately, the philosopher was a poor writer, and his thoughts are often obscure.

Philo and the Bible

Philo was famous for his exegesis, or interpretation, of the Bible. He was very influenced by Greek philosophy—unlike many of his contemporary Jews, Philo did not reject it. He believed that the truths of Plato and the other philosophers were not incompatible with those of the Bible. He found an ingenious way to synthesize Greek thought with the Hebrew Bible, or Torah: allegory. Philo believed that interpreting the Torah and the Bible in an allegorical way allowed the deeper meaning of the texts to be discovered. His commentaries on the Jewish Patriarchs, such as Moses, were also widely read.

Philo’s Influence

Philo was highly respected by the early Christians. His ideas on Logos were especially influential in Christianity; many consider Philo’s works instrumental to the development of the doctrine of the holy spirit, who along with the god the father and son form the trinity in Christian belief. His views on miracles were also influential among Christians.

Philo also wrote an account called De Vita Contemplativa about groups of Egyptian ascetics known as the Therapeutae, whom some believe were Buddhists monks. This work is believed to have greatly influenced the subsequent development of Christian monasticism. Philo’s belief that reason and faith were not incompatible had a profound impact on the development of Christian theology.

While many Jews reject Philo’s allegorical interpretation of the sacred texts, he did influence the Midrash school of Jewish exegesis, which led to the development of a large body of Rabbinic commentaries.


Philo of Alexandria was a man of two worlds who sought to harmonize Judaism and Greek philosophy. This proved very important, even radical. His concepts and ideas greatly influenced early Christianity. Finally, Philo’s ideas on interpretation also had an impact on both Christian and Jewish interpretations of the Bible.
