Where did Jesus or Paul say that circumcision was necessary ?
as you rightly point out later, paul recommends against circumcision. however, jesus said that he did not come to change the law. in john 7, he even talks about circumcision, and never mentions that people should stop.
the edict to stop circumcision has to do with removing christianity from its judaic roots. there was a lot of anti-semitic agenda in the early church for some reason. especially in letters written by paul (who also espouses slavery and the subordination of women), and in the book of john.
yes, it's against fundamentalism, but in this case, in the wrong direction. in my opinion.
Judas the Betrayer
betray comes from "paradidomi" in greek, meaning "to deliver." so his title here would be "judas the deliverer." remember, without him, there'd be no christianity.
It is a fact that God used Paul to write two thirds of the N.T.
This means that Paul and his message is the God approved message. This means that IF scripture contradicts then whatever Paul says should overrule
what about joseph smith? seriously, i can write anything i want in a bible, and publish it. is the skeptic's annotated bible also god's approved message?
in my opinion, god outranks paul's opinion of god, as far as who to believe.
Every fundementalist denomination has their own set of "circumcision" rules that they say PROVES you are a christian. In Paul's day the church was hot for circumcision or you weren't a truly saved christian, circumcision is not an issue today, but every fundie denomination has their own Mosaic list that they say, the adherence to, proves your conversion.
i've been to a lot of fundamentalist churches, and i mean a lot. every kind, baptist, lutheran, pentacostal, methodist, and even some unnamed place where they told us not to go outside alone because they had been having an alligator problem.
i've never been to a single church requiring circumcision. some suggested baptism though, which, according to the gospels, was just a temporary thing before jesus came.
