I have came across this spirit also, in "Messianics", and some Charismatic Catholics that seem offended at Paul's freedom.[WAY]
Remember Paul's struggle with the Judiazers? This is that; IE, that Jewish Born Christians effectively must have the Law and the Christ to be fullfilled.
In Israel, there is extreme persecution for those Jewish Christians who refuse to keep the Holy Days, the feasts, head coverings etc. that is demanded under Moses. If a Jewish Christian chooses to obey these institutions, he will generally be left alone. You can see why Judaism wanted to murder Paul. It stripped them of their place, position, and power.
Galatians 5:3-5 (King James Version)
3 "For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5 For we through the Spirit wait for the hope of righteousness by faith."
It is difficult to say to a person, that he or she is fallen from grace, but by adhering to these doctrines of keeping the law, we could be judged eternally. There is no Salvation through the keeping of the Law; no Heaven, for there is no Blood, no cleansing, no forgiveness, no holy fruit.
This , as I see it, is the primary reason these congegations reject, or minimize Paul, because he is so adamant as to Grace and the Blood alone; walking and living in the Spirit, as to attaining Heaven. Remember, that it was this very spirit that crucified Jesus, assasinated Him, and plagued Paul everywhere he went. They [Pharissees and Judiaizers] realized that they must do so, to keep their power. Sadly, it is the same as we see today in Messianics.
John Hagee has taken up their mantra, stating that there are even two gospels and two Messiahs, and many Christian Jews surely believe that there are two gospels; One for them including their heritage with Moses, and one for the goyim; Non-Jews. It is weird, and tragic, but it is surely a reality that we are facing.
The Catholics I confronted seemed to want to claim Peter as having the keys to the Kingdom, and be able to minimize Paul on a variety of issues;...[holy days, morality, Mariology, the authority of the Pope, etc. etc.].
Where would the Church be today without the recorded and inspired Word of God from our brother Paul. Probably we would not be here, if it were possible; The most significant man, outside of Jesus himself, in the New Testament, and right up there with the seated 24...!
