text: Law of Christ Much debate surrounds what Paul means by "law of Christ" in Galatians 6:2, a phrase that occurs only once in all of Paul's letters. As Schreiner explains, some scholars think that the "law of Christ" is the sum of Jesus's words, functioning as a "new Torah for believers". Others argue that the "genitive in the 'law of Christ' 'should be understood as explanatory, i.e. the law which is Christ. Some focus on the relationship between the law of Christ and the Old Testament Decalogue. Still other scholars argue that whereas the "Mosaic law is abolished", the new "law of Christ fits with the Zion Torah", which "hails from Zion ... and is eschatological". Schreiner himself believes that the law of Christ is equivalent to Galatians 5:13–14's "law of love".  According to Schreiner, when believers love others, "they behave as Christ did and fulfill his law".
  Antioch incident
  As Thomas Schreiner explains, there is significant debate over the meaning of Peter's eating with the Gentiles—specifically, why might the eating have been considered wrong? E. P. Sanders argues that though Jews could eat in the same location with Gentiles, Jews did not want to consume food from the same vessels used by Gentiles. As Sanders explains, Galatia's Jews and Gentiles might have had to share the same cup and loaf (i.e. food from the same vessels). Other scholars such as James Dunn argue that Cephas was "already observing the basic food laws of the Torah" and then "men from James advocated an even stricter observance". Schreiner himself argues that Peter "actually ate unclean food—food prohibited by the OT law—before the men from James came". Depending on how one construes "eating with the Gentiles" in Galatians 2:12, one may reach different conclusions as to why Paul was so angry with Peter in Antioch.
