James 3: The 2nd Jewish-Christian section is devoted to the question:

Berlin, Victory Column, 11.11.1989
What Jewish religious laws apply in the community of Jesus? This is exemplified by the question of fasting and Sabbath observance, 2:18-3:6.
The basic question is: Do the disciples of Jesus have to fast? Answer: No. Now a compromise offer is formulated: Couldn’t the Jesus disciples at least fast on the Sabbath? Answer: No.
