Apostle Paul can never write against keeping the Law, per Acts 24:14

Acts 24:14-15 ASV

(14)  But this I confess unto thee, that after 'THE WAY' which they call a 'SECT', so serve I the God of our fathers, believing all things which are according to the law, and which are written in the prophets;

(15)  having hope toward God, which these also themselves look for, that there shall be a resurrection both of the just and unjust.

If Paul believes in all the Law, how could he tell others to break the law, to not keep the Sabbath day?
