For example, Christians do not need circumcision or go Kosher in
food preparation
Tat is true. Scriptually speaking it contradicts the teaching of
jesus and god. Now people r not following it simply because of
paul.
As Jesus was not born yet during the OT time, all the
commandments and whatever instructions or promises given by God are
to the Jews: Abraham, Noah, Moses etc
Jesus is a jew. He teaches jews, go to jewish country, celebrate
jewish festivals and his miracles r performed on jews. And the idea
of messiah is a jewish idea. Jesus had said tat
anybody who follow the rules r considered great
while anybody who do not follow r unworthy in
god's eye
The last line of book of Leviticus - So Moses told this to Aaron
and his sons and to all the Israelites
Well jesus is part of tis israelites and did he say tat it do
not need to be followed for gentiles ?
