Among other things, this biblical interpretation disregards the St. Paul's teaching on purgatory and St. James' direct anathema against he principle of salvation by faith alone.
2. The doctrine of the church as expounded by the Roman church, which requires sound, orthodox Roman Catholics to regard the gospel, as understood by evangelicals, as heresy.
Notice the hesitancy and weakness of this claim. The author dares not say that Protestantism (or Evangelicalism) represents the One, True, Orthodox Christian teaching. Such a claim is made by the Catholic Church alone (and by Easterners who share the Catholic position). That is because there were no Protestant Church Councils or non-Western manifestations of Protestantism in prior to Luther.
The authenticity of Catholic biblical interpretation is proven by the record of history. Protestantism disputes the interpretations of all previous Fathers and Doctors of the Church.
lol ...
Paul taught purgatory?
