Theology of Paul is theology of Jesus Christ. There is but Pauline
Christianity, or no-Christianity. Attempts to proclaim some primeval
pre-Pauline Christianity originate in one of two extreme tendencies:
Judaic or Hitlerite. Indeed, Jews and Hitlerites are equally prone to
present Jesus Christ and his 'Christianity' as something completely
different from what the Church teaches. For modern liberal Jews, Jesus
was a good Jewish Rabbi who got carried away and was anathemised by the
Jewish leadership but he always loved Israel and did not care for a Goy;
while St Paul is the Deceiver (for the liberal Jews) who claimed a New
Faith and a New Covenant being accessible for Goyim. For Hitlerites, St
Paul was a Deceiver as he Judaised the message of Christ. Please notice
that even extreme anti-Judaiser Marcion (Markion) venerated St Paul and
never claimed there is a non-Pauline Christianity.
