I don't believe that Acts contradicts Yahshua. If I were you; I would go back and read it carefully; and try to harmonize scripture, instead of chopping sections of the bible out. This calls for understanding.
Seriously, you are missing out on a lot of valuable information.
Just because some believers were kicked out of some synagogues; doesn't mean that all believers were kicked out of all synagogues. There is no contradiction unless you make one.
Everything you said applies to you more than me. I do harmonize scripture anything the disciples wrote must be interpreted to agree with what Jesus said not the wrong way round as you are doing.
You are the one chopping sections of the Bible out to make it appear to support you assumptions/presuppositions.
Just because some gentiles were in one synagogue does not mean all gentiles were permitted in all synagogues.
