The Hellenistic and Roman periods marked significant shifts in Western religious thought. Greek culture spread widely after Alexander's conquests, blending with local traditions. This era saw new philosophies emerge, like Stoicism and Epicureanism, as well as mystery cults promising salvation.

The Roman Empire's rise brought further changes. While generally tolerant of diverse beliefs, Rome occasionally persecuted groups seen as threats. Christianity emerged during this time, initially facing opposition but eventually becoming the empire's official religion under Constantine and Theodosius.

Hellenistic period overview

• The Hellenistic period (323 BCE - 31 BCE) began after the death of Alexander the Great and lasted until the Roman conquest of Egypt

• The Hellenistic period saw the emergence of new philosophical schools, religious movements, and cultural exchanges that would shape the development of Western religions

Alexander the Great's conquests

• Alexander the Great (356-323 BCE) embarked on a series of military campaigns that expanded the Macedonian Empire from Greece to India
• His conquests exposed the Greek world to new cultures, religions, and ideas, setting the stage for the Hellenistic period

• The founding of new cities (Alexandria in Egypt, Antioch in Syria) based on Greek urban planning and architecture further promoted Hellenization
• Greek became the lingua franca of the Hellenistic world, enabling cultural and intellectual exchanges across vast distances

Syncretism of religious beliefs

• The encounter between Greek and local religious traditions led to the development of syncretic beliefs and practices
• Local deities were often identified with their Greek counterparts (interpretatio graeca), such as the Egyptian god Amun with Zeus or the Babylonian god Marduk with Heracles
• This religious syncretism facilitated the exchange of ideas and the emergence of new religious movements, such as mystery cults and philosophical schools

Hellenistic philosophies

• Notable Stoic philosophers included Seneca, Epictetus, and Marcus Aurelius, who emphasized the importance of self-discipline, emotional control, and acceptance of one's fate

Epicureanism

• Epicureans rejected the idea of divine intervention in human affairs and emphasized the importance of living a simple, self-sufficient life surrounded by friends
• The school's teachings were often misinterpreted as advocating for hedonism, but Epicurus stressed the importance of moderation and the cultivation of inner peace

Cynicism

• Cynicism, founded by Diogenes of Sinope (c. 412-323 BCE), rejected social conventions and material possessions in favor of a simple, ascetic lifestyle
• Cynics believed that virtue was the only true good and that individuals should live in accordance with nature, free from the constraints of society
• Diogenes, known for his unconventional behavior and sharp wit, served as an inspiration for later philosophers, such as the Stoics

Skepticism

• Skepticism, founded by Pyrrho of Elis (c. 360-270 BCE), held that true knowledge is unattainable and that individuals should suspend judgment on all matters
• Skeptics argued that the senses are unreliable and that contradictory arguments can be made for any given proposition
• The school's teachings emphasized the importance of ataraxia (tranquility) and the acceptance of uncertainty in the face of conflicting opinions and beliefs
