👉 Hellenization is a concept in Christianity that refers to the process of converting or assimilating non-Christian beliefs and practices into Christian doctrine. It was introduced by John Calvin, who believed that Christians should be "hellenized" when they convert from paganism or other religions. This means that Christians should adopt the language, customs, and religious beliefs of their new home, as well as their own theology and moral principles, in order to better understand and serve the people of that new land.
