"When Christians practice yoga, they must either deny the reality of what yoga represents or fail to see the contradictions between their Christian commitments and their embrace of yoga."
Yet, when we get to the time of the New Testament, syncretism was still an issue. With the domination of Greek culture throughout the Mediterranean, the Jews were forced to choose whether they would adopt Greek cultural and philosophical practices, or remain steadfast in their rejection of syncretism. Some, like Philo of Alexandria, readily adopted Greek philosophy as a means of interpreting his own Jewish faith and the Jewish scriptures. Yet others, like Judas Maccabeus soundly rejected Greek culture.
This question of syncretism was even more pronounced for the Christian faith. As an increasingly Gentile religion, yet based on the Jewish religion, would Christianity fight or embrace syncretism? In most ways, the Christian faith embraced syncretism. One of Christianity's most holy days is Christmas, which celebrates the birth of Christ. Yet, there is no strong reason to suspect that Jesus was born on this day. Christmas was merely an incorporation of the pagan winter solstice festival which celebrated Sol Invictus, the unconquerable sun, into their own religion. In a sense, much of Christian history is made up of Christianity taking over elements of other cultures and "claiming" them for Christ. Thus, Christianity has largely embraced syncretism.
So, I return to where I started: yoga. Can yoga be claimed by Christianity and made to fit with a pure Christian faith? What say you?
