Christian Stettler, «The 'Command of the Lord' in 1 Cor 14,37 – a Saying of Jesus?», Vol. 87 (2006) 42-51
In 1 Cor 14,37 Paul mentions a “command of the Lord”. The language Paul uses indicates that he is not referring to his own apostolic authority but to a saying of Jesus. The context in 1 Corinthians 12–14 makes clear that the principle he has in mind is mutual love. Therefore he must be referring to the summary of the law given by Jesus in the love commandment which Paul primarily interprets in the sense of mutual love among Christians. Like John 13,34 he calls this commandment a command of Jesus. Moreover, Paul knows a tradition similar to Matt 7,21-23.
