In reply to the issue of the Sabbath, if I/we/you, wanted to go and preach the gospel to a jew in his place of worship, it follows that we would do it when they are actually there. This is what we see in the book of Acts. If Paul entered the synagogue on any other day, he would have had no one to preach to. The fact that he went to the Jews on their day of worship is in no way proof of endorsement of this or any of their practices. It was simply a matter of taking the path of least resistance.
We have dealt with this subject in the past and I have pointed out before, that the sabbath law has nothing to do with worship or when it is to be done. The law is simply a command to rest from one's work. That's it. That's all!!! And Paul addressed this subject in other letters, as has already been shared by others, that no one is to judge another in regards to their observance of the importance of one day over another. It is hypocritical to disobey this instruction in order to accuse others of disobedience.
