The New Testament addresses the issue of dietary laws, including the consumption of pork, primarily through the teachings of Jesus and the apostles.
In Acts 10, we read about a pivotal moment where Peter receives a vision from God that challenges Jewish dietary restrictions. In this vision, a sheet filled with various animals is lowered, and a voice tells Peter to kill and eat. When Peter objects, saying he has never eaten anything common or unclean, the voice responds, ‘What God has made clean, do not call common’ (Acts 10:15). This passage is often interpreted to mean that God has lifted the dietary restrictions that were present in the Old Testament, including the prohibition against eating pork.
Furthermore, in Mark 7:18-19, Jesus declares all foods clean, stating that it is not what goes into a person that defiles them but what comes out of their heart. This teaching emphasizes the shift from strict dietary laws to a focus on moral and spiritual cleanliness.
In conclusion, while the Old Testament contains laws against eating pork, the New Testament presents a different perspective through the teachings of Jesus and the visions received by apostles, suggesting that eating pork is not sinful for Christians.
