Yes, there were Greek philosophers during the time of Jesus. The period in which Jesus lived, roughly between 4 BCE and 30 CE, was notable for the presence of various philosophical schools that had their roots in earlier Greek thought.
During this era, the influence of philosophers such as the Stoics, Epicureans, and the followers of Platonism was significant. The Stoics, for instance, emphasized ethics and the importance of virtue, while the Epicureans focused on the pursuit of happiness and the role of pleasure in human life.
These philosophical ideas permeated the cultural and intellectual landscape of the Roman Empire, which included Judea and Galilee, the regions where Jesus preached. This philosophical context could have influenced how Jesus and his followers articulated their thoughts and teachings, even if they were rooted in Jewish tradition.
Moreover, you can find echoes of these philosophical ideas in certain teachings attributed to Jesus, particularly around ethical living and the nature of humanity. Overall, the intersection of Greek philosophy and early Christianity presents a fascinating area of study that shows how ideas from different cultures and traditions can interact and evolve.
