A Little Bit of Context from the Internet
Darren Provine from Rowan University mentions that the word ‘compel’ or ‘make’ can be better translated as “impress”, referring to the legal right of a soldier to require a provincial to carry his gear one mile for him, although other theologians have indicated that Simon volunteered.
Mark 15:21 mentions Simon was “the father of Alexander and Rufus” without further explanation, apparently taking it for granted that his readers would all know who Rufus and Alexander are. We’ve been looking at Mark for ‘The Big Read’ and the Christian writer Papias, who died around 130, tells us that Mark originally wrote his Gospel for the Christian community in Rome. This suggests that Alexander and Rufus were well known to, and probably part of, the Christian congregation in Rome.
Simon of Cyrene is also mentioned in Matthew 27:32, but not John’s Gospel.
