Ryan,

The Bible says one cannot divide up a covenant that it is a unity, so I do not partition the Mosaic covenants except for discussion purposes.

Circumcision was required of gentiles to participate in Jewish Passover, for example.  The question is what was required for gentiles to be saved; it was a fair question with a disputed answer; so it was proper for the Jerusalem council to decide on it in an explicit fashion.  At the very start of Acts all the 120 were Jews and all the first converts were also and it took Peter’s vision for him to see Cornelius, to go to a gentile’s house meant you were unclean according to the Pharisees, ala guilt by association, hence a fence around the Torah.
There was a place where all 4 things in Acts 15 were done and that was pagan temples, so IMO, what the Jerusalem council is requesting gentiles to avoid those places when those types of things are happening, avoding the appearance of evil.  They could not avoid them entirely as they also served as banks and keepers of public records; but they did not need to be around when pagan sacrifices were done, promiscuity, etc.  This was so gentiles could have table fellowship with Jews, who would otherwise be grossed out.
