i doubt he called anything "the old testament" he did say to follow the romans' laws. doesnt mean it leads to salvation. isnt that what we're talking about?
The bible is the bible. All verses have equal validity even if they are contradictory. The Lord works in mysterious ways.
As long as the Old Testament is part of the Christian Bible it has everything to do with Christianity. Christianity is a sect of Judaism. Christians worship a Jewish God, honor Jewish patriarchs, revere Jewish prophets, and uphold Jewish Commandments.
nope. the hebrew bible in no way leads to salvation, aka becoming a christian. EVERYTHING changed after jesus was born. he was a new covenant. replaced the law.
